What should I write before the number when sending a text message to London?

First of all, you should open an international call on your mobile phone. Call 10086 to inquire about the tariff.

The telephone number in Britain is 07 * * * * * * *.

Send a text message to the UK mobile phone number+447 * * * * * * *.

+44 is the British area code, and the 0 before 7 should be removed.

+86 is China-_-|||. . .
