I'm in Xi 'an, and I want to charge my friends in Jilin. I bought a rechargeable card and received a text message saying that I can't charge it to other provinces. What happened?

That depends on what recharge card you bought. Some recharge cards cannot be recharged to users in other provinces. If this is the case, you need to go to the place where you bought the card or the business hall to change a recharge card.

Another possibility is that you have recharged others more than 10 times this month, because there is a limit on the number of recharging times at present, so you can only try again next month.
