Dear Colleagues,
First of all, my apologies if this issue was included in some other post, but I was not able to find it.
I have used the following tip to root my Atrix:

Everything went ok until yesterday. I left my phone charging during the night and when I woke up, the phone displayed a message saying that "SIM Card is invalid". I've rebooted the phone and everything went back to normal. 20 mins later, the same error showed up. Rebooted again, and it worked again. A few minutes later, I've tried doing some calls and the dialer looked like calling but it was not able to connect. I have restarted again, and the same happened, only that this time no data was being transferred. I checked the APN and there was none. So it seems that it was deleted by the phone. I re-entered the APN info, everything worked again, but this morning the same happened after charging. Now my phone displays randomly the following error message: "The process com.android.phone has stopped unexpectedly. Please try again.", the APN is gone and it restarts randomly. Any clue?
Should I do a factory reset?
System Info:
Android: 2.3.4
Build Number: 4.5.91
Carrier: Movistar Argentina
Any help is greatly appreciated.
Thank you in advance.
Regards,
Fernando
Hey
Some questions:
1) Does your phone if from your carrier or did you sim unlocked it using an unlock code?
2) Did you unlocked your BL?
3) Do you run any rom or mod on your phone?

similiar issue here:
yes i have performed 1 and 2.... sim unlocked and bootloader unlocked
please help
thanks
edit:
i bought the phone "new" from ebay. everything seemed and appeared new and clean on phone so i am inclined to believe that it is in fact new. i have unlocked the bootloader, rooted the phone, and entered a code to carrier unlock it. the code appears to work as i have recieved the "phone is now carrier unlocked" message. however, where my bars should be i have an X. then, when i search for a network i recieve 3 networks: 2 att's and one tmobile. I am using a Claro (dominican republic) sim card. i try all three of the searched netowrks and recieve the same error for all of them: "network with limited service found." now i have an exclamation mark in my notification area which reads: selected network (att) is unavailable.
please help!!! i leave for the DR on sunday and need this phone to work!! thanks for your help in advance!
Hi all, I'm new to the forum and need some help. I have an MF3 rooted GS4. Last night I did a factory reset and after going through the process, I received a message that said com.android.phone process stopped working. I tried to make a call and had no issues. I was also connected to home wifi so no data issues. Today I added ATT visual voicemail (worked before the reset) and couldn't get an authentication and it said check APN. I go into that and notice the settings are gone and there is no option for Phone or ATT - I also can't access any 4G LTE data. I found some APN settings, entered and then it worked. I then did one more reset to ensure all was well and start from scratch and the processed stopped message showed up again.
Edit: this also shows up each time I restart the phone. Eventually goes away and LTE Data shows up.
Why does the process show up after reboot? Is there anything I can do to make the error go away? Anything wrong with using the APN manually entered if it works?
Thanks for any help you can provide
So I found out that the APN settings stick and I have LTE, but the error shows up twice on each reboot. Hoping someone can help me to get this fixed.
so i recently bought a att s4unlocked , rooted and had a custom rom.
before installing safestrap my phone worked perfectly.
it is currently on hyperdrive 4.3 rom.
im on tmobile right now and my apns are set accordingly.
on a tmobile sim card
phones shows that i have signal. data works.
but when i pull down the notification bar it says NO SERVICE. CALLS DONT WORK. SMS DOESNT WORK
but when i put in an ATNT sim card
everything works fine.
any help will be appriciated, thank you.
You need to check the apn when on the tmob sim
Sent from my Nexus 5
SOLVED: This was being caused by the T-Mobile Visual Voicemail app. Disabling the app fixed the problem.
I recently switched from T-Mobile to AT&T, bringing over my unlocked T-Mobile Galaxy S4 (not rooted, running stock android, got the SIM unlock code from T-Mobile). After fiddling with the APN settings everything seems to be working fine, except every time I reboot I get the following text message:
From: +1121611611
122 Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code. Activate:dt=15
Any ideas? I first saw this error text the first time I rebooted my phone after switching the SIM card to AT&T, and I get the same text whenever I reboot my phone now.
Hello again. I decided to buy 2 sprint branded phones. One came sim unlocked. I used the NV method on the other. On both I can place calls, but data says disconnected. The APN's were downloaded straight from the provider (att mexico). And I compared the apn setting with a working M8 with the same sim.
I have tried full reset, and changing prefered network type in *#*#info#*#* menu. All it does is say disconnected. Am I missing something?
Update: got it working by flashing a custom rom. I used viper (selecting unlocked version on carrier select screen)
