Roaming data can cost as much as 300 times the price of domestic data, leading to bill shock. Some of the more extreme examples of roaming bills have been for tens of thousands of dollars.
Can't find the "Auto-update apps" in the settings. Where is it, please? We used to be able to tick a case for each app to avoid automatic update but this case has now disappeared. It looks like my apps don't update automatically, though.
What about T-Mobile that can use wi-fi for calling? I can't remember if it's able to use wifi for text messaging too.

Add a bribe, and welcome to India, folks!
