Adding a phone to a SIM plan

[HelenaM]

Hello. My contract has recently ended. I wanted to swap to a SIM only plan and retain my telephone number. The SIM plan I am looking at is a 24 month option. However, in the future, if I decide I want to upgrade my handset, will I be able to do this before the 24 months is up?

Basically: I wanted to know if I change to a SIM plan, will I essentially be able to add on a new phone to that plan at a later date?

Am I able to add a phone to a sim only contract?

Hello.

Welcome to the Three Community.

Sure, you can upgrade onto a SIM only plan that's 24 months long, then upgrade it later onto a plan with a device. The SIM plan will need to be at least 3 months into it's 24 month plan before you can upgrade it though.
