Play more Y-point SMS to recharge. I obviously have enough phone bills to recharge point Y. But what does it say about the insufficient balance?

If you use mobile SMS to recharge Y coins, you will be charged twice as much.

That is to say, when you want to recharge 100Y, you have to have 200 yuan phone bill to recharge.

I suggest that you can find a good friend with online banking, let him recharge your account with online banking, and then you can give him the corresponding money (punch card or phone bill), which is the most economical.

It's simpler that you can open your own bank card to go online. There is no handling fee for online banking now. You can directly do mobile banking or online banking.

I hope my answer can help you. Please accept it if you are satisfied ~ ~ ~
