Russian mobile phone number, I can call and send text messages but I can't get online. What should I do?

See if the mobile data is turned off. Apple mobile phone is called "cellular mobile network" and Android mobile phone is called "data link".

Some mobile phone companies in Russia have to make some settings before they can use the network. You can look at it online.

Open the webpage of the mobile phone company, and open интеличныйкабинет.

Check whether the network function of личныйкабине 10900. is turned off.

If everything is all right, you can try to turn off the phone and then turn it on. See how it goes.

Finally, if it still doesn't work, you can only call the customer service of the mobile phone company to see if there is any problem at the other station.

Good luck!
