No signal when i opted out International Day Pass

Hello Everyone, I am on a trip in the Philippines. When I had a stop over at Taiwan, I screwed up and opted out of the International Day Pass via text. I lost all signal from any ATT carriers. I am currently in the Philippines and still dont have any cell signal. I have used the ATT app, rebooted my phone multiple times and put data roaming on(while on wifi) How can I get my ATT signal back and opt in again to the International Day Pass? Thanks, Ryan
