did anyone resolve this issue? I just got the same problem.
I cannot seem to pick up vodafone network.

Atrix keeps restarting when making a phonecall

ok this phone a brand new, i can receive calls and text but when i dial a number and try to make a call the phone restarts
This is factory unlocked and not rooted
Try flashing a newer radio rom.
I dont want to root it incase i cant get the original rom back.
It is weird as, i have tried with every sim card to make calls and it works but when i put the 3 sim in does plays up
We experienced the same issue on some Turkish networks as well and flashing a newer radio rom fixed the problem. Flashing roms and rooting are totally different. What you need is a newer version of your current baseband ( radio rom ) sbf and official motorola software flasher " RSD Lite 5.3 "
Hope it helps.
Thank you so much for that Semseddin.
My problem solved, i just flashed it using RSD lite 4.9
Thanks everyone
Hi. I've been having the exact same issue. I've got an unlocked AT&T Atrix and I'm trying to use a Three UK sim (I'm in the UK). I'm a bit new to the world of android, can someone post a link to an appropriate Radio Rom?
Thanks for any help!!
OK after a little more web searching I've found a (sort of) solution -
"Here's a quick fix for it thou, (not permanent)....
1. type *#*#4636#*#* on the dialer
2. Chose Phone Information
3. Set preferred network to GSM only
Viola...its fixed
problem with this fix is that you wont be able to use your 3G network but the dialer should be working."
Problem is of course that you can't use your 3G connection. Hope this helps anyone else with the same issue.

Why is it always 3 that cause a problem?
When the Nokia N900 came out, that wouldn't work with 3 initially until a couple of updates later!

May not work for Pay as you go? I didn't think that it had 2G fall back?

Weird Network related issue. Please HELP !!!!!!!!!!!!!! :|

I have been facing a weird issue for a while, in my rn3 snapdragon,
when i try to call to some of the numbers. from my jio network the call never connects, i.e. it ends instantly.
I am able to call other nos. from my jio sim, so i guess volte is working fine, idk.
I think its some firmware related issue, coz facing this in every rom even in MIUI
PS: its not a network or sim related issue, coz i have checked the same sim in other mobile, and i was able to call those nos. perfectly.
Also, i can receive calls from those nos. which i m not able to call
I can't able to find solution anywhere. Please HELP!!!!!!!!!!!!!!
Any help/ solution will be appreciated.
Thanks in advance
Facing this issue for almost 5 months now, and can't able to resolve it, flashed various firmware both by fastboot and recovery, flashed various Rom both stock and custom, also tried miflash & QFiL
