What should I do if the sim card of my mobile phone suddenly loses service?

If your mobile phone can't surf the Internet normally, please check the following:

1, you can turn off the phone for 3-5 minutes, then restart the phone and try again;

2. Confirm whether there is a network. I suggest you use it in a place with strong signal.

3. Check whether there is any phone bill. If the balance is insufficient, it needs to be recharged before it can be used;

4. Check whether the USIM card is inserted. If it's plugged in and still doesn't work, I suggest you go to the business hall to check whether the USIM card is faulty or not.

5. If the traffic reaches the peak in the current month, the network will shut down automatically. We suggest you pay attention to our SMS reminder or inquire about the package product description.
