Got an Unlocked G1 on a Different Network? PLEASE READ - G1 Android Development

Please see
http://forum.xda-developers.com/showthread.php?t=444114
I created it a few days ago, We may have discovered that G1's send sms messages to t-mobile while you are using a different network sim.
Your G1 could be sending messages to t-mobile without you knowing, and you could be getting charged for this..

[Q] International MMS dont go

Hi folks. i have this prob and trying to find the solution.
I can receive MMS from overseas BUT i cannot send them. In US all is fine but not international..All settings are fine as well as data settings. Any idea ? it says "pending" in the message status and never goes
It happens with all my international contacts in different carriers. I have not be able to sent mms international all tho i have try several times, with 3 different countries, one was Romania, the other was Italy and the other was Greece. I'm more interested for Greece (my relatives are there), i have receive several mms (mostly pics) from them, from different providers ( Vodafone, Wind, and Cosmote) but every time i send one (in any of their carriers) never goes through and getting a permanent "pending" under status of mms. I have use the standard message app that came with my phone (LG G2X) as well and other apps like Handcend sms, but none goes through. Here in US all good, but not international. so i'm wondering if there is a special setup i have to do in the phone for that or our carrier have restrict this feature.. This problem is ONLY with MMS and NOT with SMS since all sms i have send there are going all through). My data program is unlimited as well and the messaging. On T-Mobile network full signal and 4g when i try. G2X is rooted but stock Rom. I have try most of troubleshooting (reboot, airplane manual set carrier etc) with no results. T mobile support says all working ok with network. Any info on settings or how i can fix this will be greatly appreciated. . Thank you in advance.

Hm.. I spoke with T-mobile the other day since I'm leaving for Australia in a couple of weeks, and they had to initiate some kind of "unlock" process so that the G2x could operate on international networks (assuming I understood them correctly). I don't know if this is simply for use outside the US or for use between other countries and the US.
But, at the time, my G2x was rooted, running Paranoid Android CM10 (build 8?). They asked for my IMEI number and things went along without a hitch. Don't know if this helps but I'm thinking there might have to be some kind of activation process to allow the phone to communicate internationally.

Thanks for the reply BUT my phone its already unlocked to work internationally (every provider that finances a handset locks it so you cannot use it with another carrier b4 the contract expires and if you need to use it then they send you an unlock code).
My problem is this : I can receive MMS from overseas BUT i cannot send them. and i'm based in US.
Thanks again in advance.

Sorry about that - I seem to have missed the part where you can still receive overseas...
If you're phone is already unlocked to use internationally, then I don't know what else could it be since you've tried both stock and 3rd party message apps. Have you tried sending via wifi?

Other carriers don't get my texts

My problem is, other carriers don't get any texts but can get phone calls from me and I can, get there texts from them and they dont get my replies. Anyone on sprint gets them. A few of my friends have AT&T and they been getting on my s#&t why I never text them back.
I show them that I have msgd them back.
Has anyone else run into this problem?
Phone is stock not rooted and my girlfriend is still on an S3 and she don't have this problem.
My dad is on AT&T and has no problem receiving sms/mms. I got a friend on Verizon and another 2 on Straight Talk. No one has issues receiving my texts or mms.
Pimpin' Like Clinton
Sprint is sending me a new phone. I couldn't figure it out and they couldn't either
Welp got the new phone and the same problem. Sprint can't fix so they have me a 72 hour window for some one from tech support to call me.
Has no one had this issue ever?
Turns out I was blocked by AT&t and T-Mobile. Don't ask how but it's fixed now

Problems with receiving MMS messages.

I have the HTC U11 Unlocked Version running on Verizon. about a month ago i switched to Android Messages because I hate verizon messages+. Everything was going great and out of the blue I no longer could receive MMS messages. I tried Textra same result. I switched back to Verizon's app and could receive them. So i took my Sims card and stuck it in 3 other phones and got the same scenario. I put my wife's Sim card in my HTC and I was getting MMS messages with Android Messages. Today i got a new Sim card activated using my G5 (Verizon version) because i read somewhere perviously to get the HTC to work with Verzion the sims must have already been activated with a phone they support that uses HD calling and all that. After activation i was now able to receive MMS messages using Android Messages on my G5. I put the new card in my HTC and I still cannot get MMS messages using Android Messages. I have also noticed my internet speeds using 4G on The HTC have dropped considerably. my G5 will consistently get 50-75mbps down and now my HTC only gets half that. Any thoughts? Could it be corrupted files in the actual OS?
Can someone delete this thread. I didn't see someone had started the same thread the day before.

OP7 Pro GM1910 on MetroPcs

Hello everyone,
I am having a problem with this phone I bought couple weeks ago. I am using it on Metro by TMobile. Only problem is that I cannot receive text messages from ATT, Verizon, etc not on the same network as me. I can receive texts from TMobile and MetroPCS numbers without a problem.
I can send texts without any problem and everybody receives my texts. Not receiving texts is becoming problem because all these apps send me Temporary Pin to log into my bank accounts. Those type of messages don't come through either. I cannot activate my Uber account, etc.
I have talked with MetroPCS customer service and as usual they do not know anything. They haven't even heard about OnePlus. When I tell them I have OnePlus, they all go is that Samsung, Motorola? You get the idea.
One more thing to mention, I was receiving texts fine until Last Sunday, which is 5 days ago. Problem started on Monday March 30/2020.
Is there anyone having or had the same problem? How did you fix it? Or any ideas? I will take any suggestions.
So far, I did factory reset = no-go. Installed custom rom=no-go. Installed both Stable and Beta latest=no-go.
I have seen online people with Verizon were having the same problem, and they called their customer service to tag their phones as CDMA-less device. Then, texts started working fine.
I know GM1910 is a Chinese version, but out of all things, text messages don't work? I get LTE, send or receive calls, and send texts just fine. One interesting thing happened. When customer service guy reset my line, I got all the messages that were hanging there come to me at once. Then after that, no new messages.
This is my last resort. Fellow XDA-ers. Help me please!
I am in Los Angeles, CA.
PS: does it have anything to do with TMobile and Sprint merging, *ucking *hit up for Metro?
We have one gm1917 on metro and one on Verizon. No problem with text messages. Are you running the international rom? Stock Android messages? Did you try enabling rcs to see if that helps?

Question T-Mobile A32 With AT&T Sim Card Won't Make or Receive Calls

Before I get on hold with AT&T tech support, I wanted to ask the experts if anyone else has had this issue.
I bought my new A32 about a month ago. It was branded for T-Mobile, but was unlocked already.
In the past, I just put my AT&T sim card in the new phone and it was ready to go (I don't mind the T-Mobile start screen).
It worked fine for a couple of weeks, then T-Mobile sent out an update and it stopped receiving texts. AT&T put in a new sim card, and that fixed the text problem, but now it won't make or accept phone calls. Calls go right to voice mail. When I try to dial a number, it just disconnects immediately.
Anyone have any idea of what could be wrong?
Thanks.
You bought an unlocked phone for a different carrier, unlocked by a third party, and updated it.
the phone can have some issues if...
1. the software version running is different (each carriers may have different versions they approved and pushed to update for their customers, hence not supporting some versions)
2. If you have unlocked and the carrier is some minor name carrier and not the main ATT then the phone may not be supported by them.
You should backup all your data to either Google or Samsung account or whatever option is shown... then ask to have the device flashed with the latest market software version from ATT. Hope this helps.

I have the same problem. Acquired a NIB T-mobile Samsung A32 that is confirmed unlocked but doesn't work on PuretalkUSA when it came to calling or receiving calls. Texting and websurfing works but call get immediately terminated and calls made to the phone go automatically to VM. I spent three hours on the phone with Puretalk tech to make sure the settings were correct. The tech had me attempt to update the carrier configuration version to no avail. It refused to update and remained at version 0.0.0. I then stuck an T-mobile sim in the phone and noticed that the carrier config version change to some series that I currently do not recall. However, I still could not make or receive calls. I then purchased a prepaid ATT sim and stuck it in the phone. The carrier config version changed back to 0.0.0 but I was able to make and receive calls. I'm putting one more call in to puretalk to make sure I've tried everything before giving up on the phone.
I recommend that you check this guy's video on youtube. He seems to be on to something:
