Unicom 3g card can only make phone calls, send text messages, and can't surf the Internet.

There are several possibilities that your mobile phone can't access the Internet:

1, wrong cell phone parameters;

2. If the mobile phone is in arrears or the package traffic has been used up but there is no phone bill, the traffic fee can be deducted; However, it should not be overdue to send text messages by phone normally. You can see if you have exceeded the maximum monthly mobile Internet traffic. If so, you can't use the internet function that month.

3. Mobile phone failures, including system failures and hardware failures, are more likely to occur in general systems;

4. Abnormal mobile phone number, including abnormal number service function and damaged number card. The former is generally a system problem, you can contact the customer service staff to inquire, and the latter needs to be handled in the business hall.

If you have ruled out the first two possibilities and haven't recovered, I suggest you take two tests in turn:

1, land exchange test. Go somewhere else and see if this is still the case. If you can surf the internet normally in other places, it means that the network signal coverage in your place is not normal;

After the first test, I still can't surf the Internet. You can change your mobile phone card to another mobile phone and see if you can surf the Internet normally, so as to determine whether it is the mobile phone or the card. If it's a card problem, go to the business hall for testing. If it is a mobile phone problem, it may be a malfunction of the mobile phone network function, and it is necessary to go to the maintenance point for inspection and maintenance.
