What about if the number is not currently in O2. Basically I have a new O2 contract and phone. I have brought in one number from a different provider and wonder if I can bring in another number from another provider to the same phone, thus saving me the need to have two phones?
It is possible if you ave a dual sim phone.
Many phones these days have that ability.
What phone do you currently have?
OK, so you need to change one number to an esim and have the other number as a physical sim.
You can then have two numbers on one phone.
The get an eSim you need to ask O2 Guide: Coronavirus Community Help and Support or pop into your local O2 store.
