Unable to open SMS link.

It's possible. There are many reasons for this situation, which may be caused by incompatibility. Apple can't open Andrew's link, otherwise the mobile phone may block this website. If your mobile phone can't surf the Internet normally, please check the following:

1. If you don't restart your phone after upgrading to the 4G package, you won't be able to use the Internet function normally.

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

3. Check whether there is any telephone charge in the account. If the balance is insufficient, it needs to be recharged before use;

4, can be turned off for 3-5 minutes, restart the phone and try again;

5. Check whether the USIM card is inserted. If it still cannot be used after being plugged in, it is recommended that you go to the business hall to check whether the USIM card is faulty or change the card for testing.

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