> be prepared for transaction failures at best to getting locked out of the UPI apps at worst Can you clarify on this? I’ve made transactions with UPI over in-flight Wi-Fi and no cellular coverage. The entire protocol does not require cellular/SMS coverage beyond the initial setup. Unless your specific PSP is doing some risk checks and signing you out, I don’t see why this would happen. The SIM-bindings are supposed to be persistent in nature. Maybe your PSP is over-eager and you should try switching?

Could be. But the choice of apps according to me range from, less trustworthy to totally not-trustworthy and so I'm out of luck there as well. Nowadays, I just enable cellular services for few minutes, recharge that damn thing, before UPI transactions.
