maleklo Posted April 12, 2020 Author Share Posted April 12, 2020 (edited) My sim was working before March and suddenly disappeared and no longer working? Does international roaming need a subscription now ?? Note that the validity of the sim 2021, active my sim on 8/7/2019 I did not change it how turn on roaming? my sim card rejected ..and my ais not work explain me please? websit ais : http://www.ais.co.th/roaming/en/signup.html Stay connected wherever you go in the world with the service that really links people together. The international roaming service allows subscribers to make-receive calls, send-receive SMS/MMS or connect to data through mobile phones, smartphones or tablets when abroad anywhere , anytime 24/7. With our quality network and global alliance, you can now roam the world with only your regular phone number. What is important for you is important for us to provide you with the best service. For AIS customers who have already subscribed to the international roaming service before upgrading to AIS 3G 2100, the service will be automatically upgraded to be compatible with AIS 3G 2100.
