Who can I call or text with my current plan?

What’s included in Unlimited Talk on our monthly plans?

You’ll get unlimited calls and texts to the following:

• Standard UK landlines starting with 01, 02, and 03 (excluding the Isle of Man and Channel Islands — and space, of course).

• Freephone numbers starting with 080.

• Standard UK mobiles starting with 07.

• Calls to and from Northern Ireland.

• Texts (SMS and MMS) to UK mobiles starting with 07 are also included. Yay for that!

What’s not included (chargeable or unavailable):

• Calls to service and premium rate numbers starting with 070, 084, or 087.

• Calls to corporate numbers starting with 05.

These types of calls aren’t currently supported by SumoSim — but we may look at adding them in the future.
