[Q] What to buy? - Touch Pro2, Tilt 2 Windows Mobile ROM Development

Finally upgrading from my HTC 620 Dash. Planning to buy used or new touch pro 2. Using as GSM phone in Mexico. There are various US prices between ATT, T-Mobile, Sprint, Verizon, Us Cellular branded phones. What carrier(s) should I stay away from concerning usability, ROM flashing, and SIM unlocking?
Any good advice would be helpful... even if it is a better phone option to buy!

You should buy the version that has the proper 3G radio for your carrier.
Unless the ATT version will get you 3G on your carrier, I'd stay away from it. The keyboard layout is different from all the other variants, as it has a row of near useless symbols on the top row (instead of numbers on every other version) and you have to hit FN to type a number.
Also, the Sprint and Verizon versions are primarily CDMA. They have some limited GSM radios for international use. But I believe they mainly just have the voice/EDGE radios, and limited, if any 3G radios.
As far as ROM flashing, there is not much difference. Some carrier specific issues, like the customized ATT keyboard just require an extra CAB to get the keyboard configuration correct.
You should try to buy the phone SIM unlocked. If the seller was a customer of the specific carrier (for instance, a T-Mobile customer selling the T-Mob branded version), they should be able to get the SIM unlock code from the carrier for free, so you don't have to pay to get it unlocked after you buy it.
Really, you main focus should be on the compatibility of the TP2 version with your carrier.

Thank you!
Exactly the information I needed. Very much appreciated!

I would wait until the binging of spring as many of the new HTC are coming out and with no set dates on the windows 7 phones you might want to try a few of them out before picking a branded phone.
As far as the Touch Pro 2 goes it's a great phone and it's a abilities a well worth notice. Great business phone but lack a lot of the social connections to it. As far as the phone being used in mexico, I would definitely look through the providers out there first. But I completely agree with redpoint73, there are many points to look at!

Diamond Now on Sprint?

I'm starting to see Diamonds for sale on Ebay. If I were to purchase one now, would it work on Sprint, even though they have not officially released it yet? Also, any reason to wait for the rumored Raphael; is it better?
Anybody switch to Diamond from Mogul; is it much better?
Thanks for your thoughts.
The diamonds you see is most likely unlocked, and can be used in any network you like.. I have no clue where in this world you reside, but US beware! No quad-band.
I'm in USA, so are you saying do not buy? Thanks for your response.

Yes dont buy unless its an American version of the Diamond...the ones on ebay are all asian versions which means that it wont work on the 3G network in America as far as i know. Judging by past posts on here by American forum members...best you will get is either Edge or GPRS if your lucky.
The American version of the Diamond should be released in july/august...best off waiting till then i would say.
Whoa! There is a lot of untrue information floating around here. First of all, Sprint runs on a completely different network than the rest of the world. So while the phones you purchase on eBay are most likely unlocked, they still run on GSM bands, which means you will only be able to use it with either AT&T or T-Mobile in the states. (Sprint/Verizon run on CDMA bands.)
Additionally, as noted - these non-US versions of the Diamond are not quad-band, and they do not run on the 3G bands used here in the states. I have one and live in the Washington DC area. I get fairly consistent Edge speeds, and slightly more dropped calls than with a US-release phone. It's well worth it to have the most kick-ass phone currently available, but it is a sacrifice nonetheless. Of course, depending on your geographic region, you may have more or less luck.
Finally, on a personal opinion note... Get off Sprint. Phones like this are always released first for the rest of the world, and have to be made with radios specific to Sprint/Verizon for use on their networks, which is always going to trail widespread release by several months at least (if not a year or longer). By using AT&T or T-Mobile, you are going to have access to much greater equipment selections on a regular basis.
I, have the Diamond in New York on T-Mobile Network, and my Edge connection is pretty quick with Opera, and as far as calls after two weeks of use I have yet to experience a dropped call or bad reception. I know this is not the same case in every area, but the fact that this device will not work in the US is not entirely true except 3G.
*Note* Neither Sprint nor Verizon will work.
The current versions of Diamond is not CDMA version. So they will not work on any CDMA networks in the US. That includes but not limited to Sprint, Verizon, and US Cellular. They will however work in the US with T-Mobile and AT&T with Edge connection. According to the FCC filing, they will do the full announcement of Diamond in the US by August 13 and PCS 1900Mhz was mentioned in the pdfs. All photos and such can not be disclosed by FCC until Aug 13th.

Advice needed: Sprint Diamond or Unlocked

Sprint Diamond is on the horizon as is the unlocked 3G US version.
I need some advice or opinions. Do I go to Sprint or is unlocked better?
I am thinking of Sprint because of Sprint TV and Sprint Navigator being built in although I do have Tomtom software and I do have a Slingplayer.
What do you think? Is it a better idea to have unlocked?
Thank you for your thoughts.

Not sure if i understand your question correctly, but here goes.
The Sprint Diamond is CDMA. The unlocked 3G US version is GSM. Therefore if you have Sprint/Verizon the CDMA Diamond is your only choice. If you have a GSM carrier (phone has SIM card ie AT&T, T-Mobile, etc.) then the unlocked 3G version is the way to go.
If you haven't choosen a carrier yet and want to know whether to go with CDMA (Sprint/Verizon) or GSM (everyone else) then a lot of factors come into play. I switched from AT&T to Sprint recently because I got on the Sero plan, the cost was too good to pass up, Sero it's probably the best plan available. I found Sprint TV somewhat useless since the quality isn't that great, the lineup was mediocre, and 99% of the time if i have the time to actually watch tv then i'm in a place that has a full size tv. Sprint Navigator is completely useless cause they'll probably try to charge you monthly for it even though the phone already has built in GPS, TomTom/Live Search/Google Maps are much better alternatives. Assuming reception is the same with all carriers in your area the only major downside i found with leaving GSM is the limited selection of phones. On Sprint/Verizon you are pretty much stuck with the phones they offer, whereas with GSM carriers as long as the phone supports the appropriate bands and is unlocked you can pop in your sim card and go which opens the door to european and asian phones.

I really appreciate the time you put into that response. I have ATT but can easily switch to Sprint. I have long travel times daily and will take advantage of the TV on my phone but as I said I do have a Slingbox.
I have noticed a lot of G-Sensor apps dont work on the CDMA Telus version so my guess is they might not initially on the Sprint version. I also think your point about having more choices in phones by being on GSM makes a lot of sense. Thank you again - your thoughts are well taken and I know it took you time to express it.

If you're satisfied with your plan then i'd just stay with ATT. You'd probably get more use out of Slingbox than Sprint TV, plus you can always load vids onto storage memory. And being able to upgrade whenever you want really comes in handy with the way HTC keeps updating their phone lineup about every 6 months.

HTC X8T (Sprint) Windows Phone 8 Q&A, Help

Okay so yesterday my dream phone came out on sprint network the HTC X8T I really like this phone a lot. to my understanding the HTC X8T Is a lot like the HTC ONE with boom sound and front faceing spekers. but yet running windows phone 8. so I am very interested In this phone.
but yet I have a lot of questions.
1. is there an unlocked version of the phone I can buy?
2. is sprint the only ones selling this device?
3. could this device be used on boost mobile instead of sprint.
4. what are the chances of a boost version?
5.why is there not new fourm for this new device?
That should be a good start thanks.
1. Unlocked version: Maybe. Sprint uses CDMA2000, rather than GSM, although they might use SIM cards for LTE support like Verizon does (I haven't checked) typically, CDMA2000 phones won't work on other networks unless those other networks also use CDMA, and sometimes not then (because they're locked). I don't know yet whether the 8XT will be available unlocked in general, or available for GSM.
2. Sprint only seller: So far as I know, yes. If there's a GSM variant, you'll be able to buy it internationally. If not, then they will probably be the only one this side of China or something. I'd expect a GSM variant, but I don't know.
3. Use on Boost: See the answer to #1.
4. Boost version: I doubt anybody here knows. You should ask Boost Mobile about that.
5. New forum: Many WP8 devices don't have their own forums. Until such time as custom ROMs or similar are possible, one WP8 device is much like another, so there isn't usually enough traffic to justify per-phone forums.
By the way, the 8XT looks somewhat liike the One, and has the same speakers, but its specs are considerably worse. Its screen is lower resolution, and I believe it's processor is much less powerful.
HTC has not announced a version or variant of this phone for anyone except Sprint, so for now, we can only assume its a Sprint only device and does not come unlocked. Considering that Sprint is CDMA, it wouldn't be wise to purchase a Sprint branded phone to use on other networks as it will most likely not work. Boost has been known to activate Sprint phones on their service, but its very hit or miss as you need to speak directly with a customer service rep, and that itself is difficult. XD

You only need to look at the radio specs for the phone. I knew it was for Sprint a full week before the tech i was on the phone with did and she was Tier 2 support with 'upcoming training for some new WP8 device' but didnt know what the hardware was.
It runs on the 1xRTT network, so wont even work on VZW. Also given that Sprint is (or at least used to be) an HTC Premier Partner its no surprise they made a phone that only Sprint would carry. Its smack in the middle of the 8X and 8S but what sucks is we are stuck with Touch Pro2/Arrive resolution on a screen thats nearly 33% bigger (4.3" vs 3.7"). Will i get one? Im still on the fence as my TP2 still does the job for me, even without native apps for Twitter or games.

A few questions on dual SIM and carriers

Time to upgrade from the S5.
It is not clear to me if there are carrier specific versions. In my case, I need to use US Cellular and Cricket. US Cell being the main one, Cricket just for phone/occasional text.
But with all the model numbers, I don't know if something like an SM-N690U1 will work, or I can make it work with a custom ROM, or do I need to be looking on swappa/ebay/amazon for a US Cellular specific one.
If you get an unlocked phone, do you get all the bands for each carrier? ie, if US Cellular has a specific model, will an unlocked phone work on all the bands as the carrier-specific one? Or just some?
Back in the good old days, these were easier questions to answer.
Thanks for any help.
Bump once jic. Really wanna know.

Getting info on compatibility w/USC is tricky,not many peeps around here are in your situation,but,I'll try to help as best I can:
1st item:
I'd change the title of the thread to show the carriers you're interested in for compatibility.
Not nitpicking,just that there's a lot of threads that discuss the topic,& a lot of peeps might just blow right past it.
Best to give an idea of which carriers you're dealing with,it might just grab the attention of someone on US Cellular who can give a definitive answer.
Admittedly without the IMEI in-hand,this is of little use,but a starting point nevertheless:
https://m.uscellular.com/uscellular/app/device/bring-your-own-device/
Talk to a CSR & see if by off-chance,they may be able to determine if the SM-9600 (SEE BELOW) will work.......
You can rule out the SM-N960U/SM-N960U1/SM-N960W as none have root or a 2nd SIM Slot.
The Exynos version (SM-N960 F/DS) is dual SIM & rootable,but lacks CDMA bands,which may affect usability w/US Cellular.
You might have some luck with the SM-N9600 (Int'l Snapdragon version w/dual SIM & rootable),but,not knowing how US Cellular treats BYOD,IDK.
Check this compatibility tool,it looks like you might have some luck with the SM-N9600:
https://www.kimovil.com/en/frequency-checker
USC is the monkey wrench in the mix here,being they're a MVNO of VZW & IDK how much of the CDMA part of the network affects your service area.
If you really need a dual-SIM Note 9,you'd be better off with both service providers being AT&T/T-Mobile or any mix of the two & the MVNOs associated with both.
One possibility to consider:
If you're only needing data from one SIM/service provider,but,want two (or more) numbers on the same device,you might want to consider T-Mobile & their DIGITS option:
https://www.t-mobile.com/offers/t-mobile-digits
What's nice about DIGITS is it'll work on any phone,only one-SIM Required & it doesn't have to be a T-Mobile branded phone.
So,if you're wanting root & the use of two phone numbers,you can have both with either a Single SIM (SM-N960F) Dual-SIM (SM-N960F/DS) or the SM-N9600 (I think it comes in both single & dual SIM models).
Again,I wish I could be more definitive w/the suggestions,but,there just isn't much info regarding US Cellular out there.
Your situation is one of the main reasons I left Sprint & choose to stay away from service providers that use CDMA as part of their network,it really limits your options for BYOD.

SM-G973F/DS in USA? Waste of time?

Long time lurker, first time poster here. First of all, a massive THANK YOU to everyone here. You guys and gals are Awesome! <3
So, I bought a Samsung S10 (SM-G973F/DS) on Ebay recently and flashed it to Lineage OS 19.1. All was fine until I tried to activate it. We did everything...manually changing the ASP settings, and a bunch of other stuff to try and get this thing to connect to the mobile network. Even placed the SIM card in another phone just to confirm the SIM card was fine, which it was.
Long story short, I think the device was perhaps locked even though the seller claimed it was unlocked. Whatever, I'm over it. I flashed stock back on it and re-locked the boot loader, sent it back. Not worth the aggravation. However, I am questioning if there wasn't something else I could have done?
I was trying to activate the S10 on Mint Mobile USA (a T-Mobile reseller, so GSM) it should have been fine. The default language on the device was German. I don't think that should matter, but maybe it does? Do European phones have problems activating in North America?
My question is: If I decide to get another S10 (SM-G973F/DS) from the secondary market (if its even worth it at this point, since the SM-G973F/DS is really hard to find), is there anything I can find out from the seller first so I don't end up having to send it back?
Or, should I just give up my dream of having an S10 installed with Lineage OS and it's glorious headphone jack and expandable storage forever? If so, are there any worthy alternatives to the S10 worth considering, given my affinity for headphone jacks and expandable storage?
Hello PhonePerfection, all a novel why you speak S10 G973F / DS in the United States.
Already your model S10 G973F/DS exynos 5G or the first 4G model so if these this Europe chip model, if now installed Samsung phone info look at who is scoring at worst take screenshots.
I don't understand your question United States, locked unlocked the seller.
You buy in the back market refurbished and unlocked telephone all operator therefore for sim card, the concern these the chip to install network either US or ASIA controls your model if these good SM-G973F/DS and not SM-G973U or G973U1.
Don't forget to say hello
I think what @meric57 is trying to say is that your phone doesn't have the right chips to communicate on the frequencies in the USA. It's made for other markets and other frequencies... so it won't work here.
If you use FrequencyCheck you can see what carriers support what frequencies on your specific model: https://www.frequencycheck.com/comp...m-td-lte-512gb-samsung-beyond-1/united-states
Scroll down to the "United States" area and you'll see it doesn't support the frequencies used in the USA (except for GSM 2.5, which is old and dead here in the USA). The US is primarily on LTE... and you can see that phone model doesn't support ANY of the available frequencies.
Bottom line "GSM" doesn't tell you enough. You have an incomatible phone model for the USA market. No SIM card will fix that.
Note, in SOME cases, you can activate other frequencies by loading different ROMs into the phone. My old LG V30 did this, for example. I have heard that you can run some Exynos phones here in the USA, but I don't know the details to help. FrequencyCheck may help you figure that out. Be sure the look for the complete model number, not just "Galaxy S10" or something... the naming is worthless for figuring this out.

Hey, this is great info. Good to know. It looks like that S10 could only communicate on 1 of 8 bands used by Mint/T-Mobile. That 1 usable band appears to have been deprecated by T-Mobile as it is. I think that explains it perfectly. Thank You!
You're welcome.
Yeah, frequencies/bands are very important to watch, particularly if you're buying out of market devices. You have to know model numbers and carriers to be sure of anything, and unfortunately this info is relatively hidden.

The CSC on that device was DBT (Germany). I had to find that out in order to put the correct stock OS back on there.
Makes me wonder if the ebay seller even knows this. They appear to specialize in mobile phones with tens of thousands of transactions, so I would hope they've encountered this situation before. They were more than happy to accept a return on the device. Sent me a prepaid shipping label immediately.
Back to the CSC... Let's say I look for another S10 (SM-G973F/DS) but I ask what the CSC is for that device. Are there any regions outside the lower 48 states with reasonably good chances of it working? I suppose I would need to study the mobile frequency website for the answer to that.
I did some quick searching, and supposedly there are websites that say the 973F/DS will work on MM (mint mobile)... but they don't detail how. For example: https://de-googled.com/blogs/news/a-word-on-network-compatibility-of-our-degoogled-phones
and https://www.ebay.com/p/15030406771 (in the description).
So, maybe it is possible? I don't know, so maybe someone else can chime in.
Personally, I stuck with U-version phones and gave up rooting/romming. It's just getting too hard to find phones that offer this, so I figured I'd just adapt back to a stock ROM, since choices are limited. I had done a bunch of that in the past, but I found that stock roms (today) are pretty good... and allow enough customization that made root/rom unnecessary... for me. My current is an SM-G975U1 (unlocked, USA, Snapdragon S10+) on Total Wireless (VZ MVNO)... it works great and I don't miss root/rom at all.
Rumor is that the Galaxy S23 will only be offered as Snapdragon, so maybe that will open up more options... but I doubt it. Samsung loves it's Knox system, and will likely lock down the phone even more with every generation.

Thanks for the link. I think I may try for an S10 again if the seller can tell me what the CSC is. That page on De-googled.com affirms that American devices are more restrictive than their European counterparts.
It just doesn't make any sense to me personally to use a device with an open source OS that has loads of telemetry, spyware, bloat, etc. Which is a contradiction that I am not comfortable with. It's like installing a Linux distro that comes bundled with Facebook.
To me, being proactive about privacy is the equivalent to standing up for yourself in the real world. Sure, you can use a stock ROM and there is nothing wrong with that. It's having the freedom to choose which is most important. So long as that choice is available, I will happily go that route.
I like the added bonus of an Android device that seems faster with a longer lasting battery as well. I mean, I paid for this device. I should have the right to decide what apps are running on it.
No argument there... I agree with why we should be allowed to root/rom. Unfortunately, the carriers pull the strings in the USA (business over people) so we are losing options. Frankly, it pisses me off that they can still prevent phones from connecting to their network just because the IMEI doesn't match (even if the software is correct). In the end, if the device CAN work on the network, the carrier should have no say in allowing/disallowing it on the network. They like to claim that a "bad" device could "hurt" the network, but if that happens, they can lock out that phone and figure it out. I doubt that's even ever happened, but whatever. (They prevented me from using my already-working V30 US998 phone on the network, even though it ran as VS996 with no issues for years... they only later saw the IMEI wasn't "theirs" (original SIM card failed) so they prevented me from re-registering it. So stupid.)
Good luck, and let us know if you figure it out... I'm always curious to learn!
yes, most japan and europe phones do not have the correct radios channels in them for 4g and 5g. i ran into this same problem with my xperia phones that i bought overseas. this is a common problem that can happen.
The S10 and all it's variants is a world compatible GSM phone. So yes, the F variant should work with most GSM carriers and resellers in N. America.
There are various websites that will tell you what frequencies and carriers any particular model will work with if you do a search. Like this one.
WillMyPhoneWork.net - Check if your phone works on a network
Check 2G, 3G, and 4G LTE Network Frequency Compatibility for a Smartphone, Tablet, and Mobile Device in any Country and Mobile Network Carrier
willmyphonework.net
According to that site the SM-G973F/DS supports all 2G, 3G, and 4G frequencies used by Mint.
