You have never heard of such a data-saving method: SIM card saving method,
Tutorial starts:
Point the SIM card to your eyes with the words [make the notch in the lower left corner]
Count from top to bottom, the second contact on the far left, and stick it with transparent glue.
[Maybe the card is different, so it's best to try each contact once, if it's really not good, that's the problem with the card!] 〕
After sticking, be sure to let the mobile phone read out the SIM card, and the access point should be set to wap!
It's done, the move is successful, only 0.87KB was used on the first day, almost no traffic is needed, and only 10KB was used to play games on the second day, this method can also save phone bills.
I have been using this for many months, and this method will benefit me for life!
