Unable to make or receive call while in roaming on GSM in Motorola DROID PRO

Folks

I have rather odd issue with my Motorola DROID PRO in eu on GSM/UMTS network. And this happen while i’m roaming and use GSM only no UMTS my mic and speaker get dead. I be able to build a call plus receive it, but i can’t hear nothing and caller doesn’t hear me. Display show seconds have past so line is connected . i be able to still receive SMS plus MMS just fine as well as send them, just calls don’t operational

Now I modify from GSM to UMTS merely, then calls work very well. When I’m on residence network the whole thing is okay.

Funny thing is that if I build a call on roaming in UMTS only in addition to then alter to GSM just I can receive earliest call, subsequently it's all clear once more.

I actually stock ROM

I don’t think anything wrong with the phone most likely the issue is through the network where you was situated. Did you try a different network?

My Motorola DROID PRO works perfectly ok while I am in roaming, in together GSM and UMTS.

Got the same problem

Voice as well as Data Work fine in 2G 900/1800 MHz
However No Voice, Phone re-boots only Data works in 3G 1900 MHz

So I have to make use of the handset in GSM only mode.

I am using 2.3.3 with the Verizon 4.6.4 update.

I have Motorola DROID PRO which was working fine with the old operator although after shifting to the new operator i am also facing the similar problem which is in the particular place I can't create or receive a call in just in 2G but I can send or receive SMS as well as data traffic is ok . However if I modify in 3G I be able to do the entire thing perfectly fine

For my operator it is a problem between SIM by ORGA and Motorola DROID PRO and so I'll swap my SIM

I did not able to get the non ORGA SIM however I did purchase a twin SIM adaptor, for considering Nothing found On my operator which is TIM while I’m on edge in only similar locations, i can't make or receive calls Not with my ex operator which was wind

However you be able to try to type on your dialer ##7764726 then call, then password 000000
• Then verify 06 test mode
• Tap next
• Again next
• Then on the service option switch to 13k, or others, then exit
• Now Make a call, or else try this configuration
Don’t restart your phone if you didn’t than follows this steps again
