Well it won't matter, unless you want to keep the phone as one or the other. If you want to use sprint, you have to have a sprint phone. If u want to use at&t, at least for volte (I believe), u have to have an at&t phone.
But if you're going to use an mvno, and cross flash the device with say, Open US android 9 (10 isn't available yet), then either one.
I tend to prefer at&t. They can be gotten in 'unlocked' (to carrier) state more easily it seems. But others have used sprint with no issues. Just be sure neither one is carrier locked, because there's no way to unlock them now without the carrier doing it.
cheers

[Q] International usage / bad ESN

going to be in the US for the summer and am strongly considering buying a HTC One.
first thing i will do is root it.
problems..
when i come back to europe am i going to be able to use the phone orange even if it is the sprint or at&t version?
mainly what i want to know is if the sprint version for example is locked on sprint just by software or also by hardware..
if i buy a clean/bad ESN one will that be in conflict with the carriers in europe?

[Q] Questions about Sprint Unlocking

So I see there is a thread about unlocking your phone in these forums but that says its a GSM unlock. I have no idea what I'm doing when it comes to unlocking phones but I know I want to use my sprint M8 on Verizon since I'm switching services.
So my question is, is there any way to unlock my phone to work on the Verizon network? Is that unlocking method make it work on Verizon or just ATT?
Sorry but I am extremely ignorant on the subject and am looking for some info, rather not rebuy my one.

Hi, extremely sorry that no one took the time to respond to this sooner. I believe there is 2 methods to do this, one being a SIM unlock and another being the GSM unlock you mentioned above. To my knowledge GSM unlock is what you want but sadly I don't think there is any 'free' way of doing this. I've never personally GSM unlocked one of my own phones but I have helped a friend do so. Anyways in order to GSM unlock a phone you need a special 'generated' (i think generated) code to input in your phone which will unlock it and allow it to use other carriers besides the one it was made for.
Here is a presumably valid tutorial on how to do this on an HTC One M8.
I would recommend trying freeunlocks.com first, only because I have a coupon from there which i'll gladly give you if you plan on using it. Only reason I have one and or am giving it away is because previously I bought one from there and they didn't have a code at the time so they refunded me and gave me a coupon code to enter if I ever purchased from them again which I most likely won't as I have no need for GSM unlocking, i.e why i'm giving it away. If by some chance freeunlocks does not work then you can try the one in the video or you can look for others.
If you would like to try this and want the coupon for freeunlocks.com then just say so in your response and I'll PM you it. I think its for either a discount or a free code, I don't really remember as this was quite a while ago when I was given it. (around a year)
Goodluck!
I'm just not sure if this would work because I'm trying to go from sprint to verizon, both being CDMA. If I did this would it mean I have to go to ATT?

I don't think so, according to this it should have all the proper bands to support both Sprint & Verizon. On the off hand there is always the chance that this link I just sent is ONLY for the International model and I am wrong which I very well could be. I've had trouble truly understanding if all versions of phones have support for the same bands or if they don't. I'd recommend researching this a bit or waiting until someone else comes along with the proper knowledge to assist you in your question on the radio bands comes along.
Anyways LS;DR, It should work but I may be wrong so do your own research or wait for someone else with the proper knowledge to assist you to come along.

[UNLOCK] What to do now?

Hi everyone,
i got a Sprint HTC One M8 from ebay, it is new but i was planning to use it on AT&T network, since it have a Sim Card Slot. Furthermore, even though i'm living on the US now, i'm from Brazil and i was planning to use the phone there as well.
And now starts the problem.
I called the previous owner, asked him to contact sprint to make the sim unlock procedure. He did so, providing me the MSL for the phone. The next step, he said, was to "flash" the phone on AT&T in order to get it connected to their network. I tried several sims, even bought a new one and activated it but with no success.
I spend almost 2 hours on the phone with the sprint's international support, and all they said was that they did everything that they could about unlocking my phone and now i should contact AT&T.
I'm afraid of staying on this infinite loop and i want your opinion.
Does anyone in fact unlocked their SPRINT phone to use on another GSM US carrier? If yes, what did you do? Because i'm planning to return the phone and ask for my money back.
BUT, with the "International Unlock" i should be able to use the phone on ANY international carrier? Because if that is the case, maybe i keep the phone to use when i go back to Brazil.
Thank you very much!

On the CDMA version of the M8, it lacks the LTE bands needed for Domestic carriers. You can use it overseas somewhat, but not too well. If I was you, I'd grab a Droid Turbo for ~$200-$250 off eBay. It just recently got its bootloader unlocked finally

V40 upgrade from V30

Have a V30 now and because of their prices, have considered purchasing another as a backup. Looking at Swappa, I see the V40 is less than $100 more expensive and rootable.
On AT&T but hate having the logo on the back, so buy either international or unlocked. If I were to buy a Sprint, carrier unlocked V40, and flash Pie, for instance, what modem will I be using? Can I use an AT&T modem for? I know on the V30, the US998 covers everything...just wondering how it corresponds to this.
Also wondering how much of an improvement the phone is over the V30. Biggest complaint I have is the ability to see the screen in daylight. Everything else is fine, for me.
Thanks in advance!

So if you buy Sprint V40 it's carrier locked unless you can verify that it has been unlocked for other Sims....and if you do upgrade to Pie it would be US unlocked Pie which uses the unlocked modem...but it will still keep the option to update PRL and Profile...but apn settings will be able to be edited...that I'm aware of the network unlock should still be present once you go from Sprint Oreo to US Unlocked Pie....

Saw it on Swappa from someone I have used before, stating carrier unlocked. APN should be set by SIM card so not worried about that.
Concern is having the correct bands for use in AT&T vs Sprint, 1, and 2, is it worth the <$100 upgrade from the V30 to the V40?

If the US unlocked V40 acts like a Samsung S9/S10/Note 10 once you pop in a different SIM card it'll recognize it, reboot, and apply the correct settings for that carrier. This might help with your modem concern as I'm just talking out of my rear right now, but maybe the unlocked modem has the correct carrier info.

This is usually the case but was not sure what modem would be applied using the bootloader unlock method.
Biggest wonder, though, is whether this phone is worth the extra $100, from a real world perspective.

Advice for getting a v40

I want to get a v40 to replace my Redmi Note 7
I use T-Mobile but know not to get the T-Mobile v40. So I was curious if it would be better for me to get a different one and unlock it or what should I do?
Any advice would be great because I don't want to put my self in a pickle where I have a nice paperweight
No need to get a TMo version.
A cross flashed Sprint V405UA to LG v405QA will work on TMo and get all TMo bands, plus TMo VoLTE and TMo VoWi-FI and TMo HD Voice. I know because that's the model I bought, cross flashed, and use on TMo.
I see no reason why a cross flashed Verizon or ATT wouldn't be equally good. But I can't speak there from personal experience.
But there's no cross-flashing possible on a TMo version. Once TMo, always TMo.

I saw you in some other posts and I was hoping to get you to respond to this. Thank you. I'll have to keep my eye out to see if I can find a sprint one. I like my redmi note 7, but there are many features that I want that it just simply doesn't have. But are there any other weird quirks I should know? Again, thank you.
Thanks for kind words. I seem to have a bit more time on my hands now ... I wonder why ....
The only weird quirks I think are worth mentioning is that it is not easy to root and install TWRP. Several have had issues doing so. It can be done, I and others are living proof, but it's not for the fainthearted. You'll have to bounce back and forth between several threads to get it right. There's no one comprehensive guide. If you're not looking to go that route, there really are no quirks.
As for sourcing one, I picked up mine, a mint condition device, off of eBay for $145. A steal for a phone of this caliber. They seemed to have upped the price in the meantime.

Troubles with getting TWRP working don't bother me. I don't mind that. I love messing with things a little too much. Also, with that link that you sent, although the listing said you can't use third party software to unlock it, you still can. Correct? (Well the listing you sent said that it was sprint only, but not specifically unlocked. But it showed me a similar one that is $170 that says it's sprint locked)(also that because it technically isn't software that you're using to unlock the device.)
And I do wonder why you would have more free time on your hand, I could never tell why...
In many cases, these eBay vendors have no idea what they are selling or what "tethers" come with which phones. See here's the thing. If the device is paid off, it can't/shouldn't be carrier locked. You own it free and clear, and should be able to put it on any carrier with which the phone is compatible.
From reading these forums, I knew I could convert (cross-flash) a v405UA (Sprint) device over to a v405QA (US version) which would enable more bands (that I needed/wanted for my eventual migration to TMo). And if the device in that listing was somehow actually carrier locked to Sprint, I knew I could get Sprint to unlock it. I had Sprint, I knew I was going to use the v40 for a while on Sprint, so I could easily verify its carrier unlocked-ness, and could correct it if needed.
But I didn't need to. The v405ua (which was originally attached to Sprint at some time in the past by a different customer) came to me carrier unlocked. Three weeks later, I had that same device, crossflashed, rooted, with TWRP, on TMo happily making use of the extra TMo bands, VoLTE and VoWi-Fi, and HDVoice (none of which a non-crossflashed v405UA could).

Ok, so if it isn't paid off then the seller is selling a bad phone, and they should list that in the description.
I'll buy the $170 mint condition v40 because it's a good price for the phone, and I'll have something to mess with. Thank you, again. I appreciate all the help.
It'll be nice to have a nicer phone again. I loved my S8 before I broke the screen, and after I had modded it.

I have gotten twrp working along with being able to install linageos
Only issue is that it asks for a password and I don't know what to do from here. I need to sleep.... I've been at this for far too long

Took me like 3 minutes of reading. After wiping data it is fixed. That was easy
