Roaming not working in Thailand

Level 2


I have a TPG/Optus SIM and I've enabled global roaming before leaving but it wont connect to any network in Thailand.


I've spoken with tech support twice without luck.


Things I've tried:

-Tested in two phones, both of which connect to DTAC and AIS networks with local sims (also my Australian Boost/Telstra SIM is able to connect to AIS even though roaming is not enabled on that SIM).

-Tried connecting manually to each of the networks in Thailand (AIS, DTAC,TrueMove) with both phones.

-Tried with 2G only, 3G/LTE preferred.


Any Ideas?
