Hi, i'm using Mi2A, still on MIUI-3.10.18, didn't have time to update yet. My current location is in Jakarta, Indonesia, and i have Postpaid Telkomsel (Kartu Halo) as my provider. Last week, i went to Singapore, and i couldn't connect to every networks there. Telkomsel has Singtel as their partner, but i couldn't event click on Singtel button to connect (grey and unclickable). I tried automatic search and manual search, found another 2 networks (forgot their names) but couldn't connect. My questions are : 1. Is this ROM issue or something else? 2. Is this happened because i haven't update my ROM? 3. I want to know Singapore's Mi2A owners experience, because i have to go to Singapore frequently. Thanks.
