Odd Mobile Connection Problem

[dddave]

My friend lives in Koh Samui and uses D-Tac for mobile service.  I'm in Jomtien, using AIS.

We normally speak daily.  The last three days, whether she calls me or I call her, the call immediately terminates when answered. Just a quick "BEEP" and gone.  

Neither of us is experiencing difficulty calling others.  Both accounts are up to date with payments.

Difficulties with different providers interfacing are long in the past AFAIK.  I can't figure out what would make this happen.

Have either of you tried calling your providers and speaking with them?

But do you mean calls using the paid telco link, or using the free LINE link?
