[Q] Can I use an Inc s cdma (verizon) ?

Hello,
I have an htc incredible s for flashing; but it's an cdma device (verizon); when I'm configuring it I have an error message "Unable to activate you phone. You may need to find an area with better coverage (near a window, or outside). Please try again or call custom service for more assistance."
We haven't cdma technology in my country, then I want to know if I can use it as gsm device or no ?
Thank's

Of course not, it's a different technology, and as far as I know it doesn't have a sim card slot. Try to google it.

you mean find a solution on google or something else?

You will not find a solution to use CDMA for GSM it's mission impossible.
You don't have a SIM card slot so you can't use GSM SIM card.
By google it I meant to find difference between CDMA and GSM to understand your mission imposible.

No 3G!! service loss when on "cdma only" mode

My phone is sim unlocked, using viper one rom, i'm always stuck on gsm even though my carrier "ooredoo algeria" supports 3G, i have checked and the cdma network frequencies are well supported on the device, how do make i the phone use 3G.

Have you tried going into *#*#4636#*#* and scrolling to the bottom, and changing the frequency to WCDMA only? Also, if you have a SIM card, your phone is GSM. CDMA phones are always without SIM cards, unless they support 4G (since 4G needs a SIM card to work)

ooredoo dz network mode switch must be Automatic

Hey Abdou, you have to put your network mode on "automatic" and ooredoo's network will choose the right netmode for you

Problem solved

Thank you for the reply, but i already fixed the issue, i was a noob when i asked it and i didn't understand what cdma and gsm meant i thought cdma meant 3G, but now i know that UMTS means 3G haha, and that i am on a gsm network, i figured it out.

Sprint HTC One unlocked to GSM Data problems

Hello, I have gsm unlocked my sprint htc one and I'm now using Metro PCS network. Calls and Text work just fine but, when it comes to mobile data it runs super slow and I have no clue why. Any help appreciated.

Check your APN settings in Settings > Mobile Data > Access Point Name to see if they match these: http://unlockandrepair.com/metropcs-internet-mms-settings-for-android/
The other thing is that the Sprint HTC is primarily a CDMA phone with GSM cabability and the GSM bands may not get you fast data. For instance Sprint LTE band is 1900 whereas T-Mobile's LTE bands are 700, 1700/2100.

Yeah I'll give those APN settings a shot, I'm using T-Mobile's apn settings. Yeah I had read about the radio frequencies , when I first unlocked my phone to gsm no network providers other than Sprint would show up ... So I flashed a T-Mobile radio through twrp.

The bands are hard wired into the phones, the Radio you flashed just enhances the bands capabilities but can not add bands.

Oh I did not know that. Imma try out the settings.

[Q] Virgin Mobile HTC Desire 510 on GSM Networks

I got a Virgin Mobile HTC Desire 510 4G NoContract Cell Phone Black at Best Buy during Black Friday. If I manage to get it SIM unlocked will it work with GSM networks? Has anyone done this?
Thanks!

No. From the looks of it, the Virgin Mobile variant is a CDMA only device. So it doesn't have the hardware necessary for GSM functionality.

Buddy but htc 510 is global device ...?

Any progress on checking with gsm networks.

HTC Desire 510 Virgin USA
Hi there,
I wish to know if you could guide me through some alternative approach to unlock for HTC Desire 510 Virgin Mobile.
This is a no contract phone with Virigin Mobile USA.
I am sure it has the GSM Capabilities as well, when I looked at the usermanual, it has an option where I Can go to settings and change if only GSM or CDMA can be used.
I purchased an unlock code from another service provider online. Followed the steps. When I insert another sim card, it does not prompt me to enter the Unlock Code and the phone keeps saying Invalid Sim.
Would you guys be able to help.

Are there any other options on your phone?
On your phone, do you have any options other than: LTE/CDMA and CDMA ?
Thanks !

Yeah sprint htc 510 can be unlocked but not for domestic use it can be unlocked for international use..!

Can it run on a GSM (instead of CDMA) network?

Ok, thank you! I know it can be unlocked, both the SIM and the boot loader, but that was not my question. The question has to do with the network. On the settings shows LTE/CDMA and CDMA; for it to work on a GSM network it would have to say something like GSM 2G, GSM 3G, GSM 4G or something like that.

I have the same question about this phone, I bought it on Cyber Monday and an Amazon Customer Agent told me that is a GSM phone. On the phone you can type * # * # 4 6 3 6 # * # * and a menu will show and you can change between some options include GSM/GPRS/LTE/CDMA/WCDMA.
Currently I'm searching the way to unlock it to use any network but still without nothing :crying:
If you have any option to us we placed you!!

hi bro, I try to root but I could not unlock the device, got some method?

Virgin HTC Desire 510
Hi All,
I am in exactly the same situation. Bought the phone expecting to unlock but not able to. I bought an unlock code but of course there is no prompt for the code. In network options I only have CDMA/LTE or CDMA.
Has anyone succeeded in unlocking?
Thanks!

Hello everyone.
As i didnt want to open an new topic because i found this one.
I am from Greece and i got this phone as gift from my uncle., the phone is setup at CDMA network and does not have the GSM/WCDMA setting. when i get into the *#*#INFO#*#* i can see there that i can change the network type to GSM/WCDMA/LTE but i dont know how to save it. does anyone know any method to make this one work properly?

Unlock GSM Bands
You don't have to do anything to save it. I would bet that you can change it and if you wait a little while it reverts back to CDMA. I think it reverts back because the frequencies needed for GSM/WCDMA/LTE are locked. I would recommend http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 and unlocking the following bands:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 2100
4G Network LTE 800 / 1800 / 2600
After you do that, my guess is that it will accept GSM/WCDMA/LTE. Beware that I have not done this, but that's what makes sense to me. Let us know the outcome. Good luck!

No I not finish, have a trouble with the step 10 in the tutorial, and cannot continue.

Do this:
adb shell
su
cd /sys/devices/virtual/android_usb/android0/f_diag
echo 1 > on

Windows should automatically try to find the drivers... if it does not use the drivers on the original post. If windows finds the drivers you should have a new Com port and you can go to step 14.

SM920P Can't establish wireless data connection troubleshooting

Hi guys,
I bought a SM920P Note 5 (Sprint) in , I could use 3G at VietNam without any problems but when I arrive at Japan, I can't use 3G anymore, only ordinary phone calls and SMS. The phone keeps alerting this error : lte:esm - 29 emm - x unable to stablish a wireless data connection.
I have entered the APN setting of the carrier. I tried to put the SIM into another phone and it works without problems.
In the settings>more>about device>status : the networks says HSPDA. So I changed the Bearer in the APN setting to HSPDA but still no luck !
My OS now is Nougat, and I don't think the phone is rooted because I'm receiving auto updates.
Does anyone know how to troubleshoot this problem?
Forgive me if there were missing information, just ask me and I will provide, sorry I'm not very "technical" !

Thanks for the reply.
I only have 4 mode in my network mode :
- CDMA
- LTE/CDMA
- GSM/UTMS
- Automatic
If I chose CDMA or LTE/CDMA there won't be any signal at all, the working options are GSM/UTMS and Automatic which I assume is the GSM/UTMS itselft.
Any ideas ??

Did you get Sprint to unlock your phone for a different carrier before you left? Those APN settings have to be set exactly right and you must save it. Once you change your network mode it may take a bit to get signal.

No, unfortunately I bought the phone in Vietnam, are there other ways to solve this? Like rooting the device and make some system changes?

I do not know if rooting it would do you any good. I am not sure if changing the firmware would allow you to change carriers. I am not even positive that's the problem. Did it ask for some kind of code after you inserted the new SIM?
Is it a data only SIM? I think it needs to be a data only SIM being a CDMA phone.

Hi RedNeck, sorry for the late reply.
No it did not ask for any code when I inserting the SIM, the SIM is capable of Call and SMS.

No problem. I could be wrong but I am pretty sure your Sprint phone is CDMA and I am pretty sure that the only thing your phone uses your SIM card for is LTE data. So if I am correct you need a SIM that is data only. The other phone it works in, is it CDMA or GSM?

Actually I don't know anything about the CDMA or GSM things. Here is the result I got from googling the spec of the other phone :
Technology
GSM / HSPA / LTE
So, assuming you're right, can I just "disable" the calling and SMS function of the SIM, make it to become a data only SIM? I already got into a 6 month contract here, so I can't change the contract type in about 5 months !!!

You are welcome. I do not think you can do that to a SIM. The other phone sounds like a GSM phone and if the SIM works in that phone it will not work in a CDMA phone. I would go to your new carrier and ask if there is anything they can help you with. That's assuming that you are not carrier locked to Sprint. Then you have the fact that the CDMA SIM will not work in your other phone.

Thanks, but are you sure this is a CDMA Phone? Because when I change the Network Mode to CDMA or LTE/CDMA, the phone will lose all the signal?

Yes I am sure. I have seen CDMA carrier phones that were refurbished by third parties that "claim" they are unlocked for GSM carriers. I am not sure how much I trust that. You may hit up Sprint support and see if there is something they can do for you. If you bought it on contract from them they may not do anything for you.
Good luck.
