Setup check for my Android phone

SquareSwallow:

one of them is impossible due to not having a website at all and is for calling cabs similar to Uber, the other is a shopping app which is possible but their website has some key features missing

Okay I get it. I pointed out that out since many western e-shopping websites have feature parity between website and app, but that may not be the case elsewhere, especially in Asia.

SquareSwallow:

but there’s no way for me to reload my SIM without an app and to purchase a data plan.

that’s strange. if it’s prepaid can’t you buy physical top-ups and enter them with a SMS/phone number ?
