I'm about to move abroad. My time will be split with the other country (covered within my plan for international roaming) and the UK, but with the majority being abroad.
I anticipate I will be getting a local SIM card with data, but want to keep my UK phone number, and ideally, my UK contract. I am happy to have it set so I only get incoming calls on my UK number, and all outgoing calls are via my local phone number.
My phone has one physical slot, two eSIM slots, and is fully unlocked from O2, so technically there should be no issue with me having multiple SIMS and contracts.
The problem is, I expect to be breaching the fair usage terms for how long I will be outside the country.
The simple answer is for me to switch the SIMs in and out as I move borders, however, I'm unaware of how apps such as Whatsapp will work, which I believe is linked to my phone number, not the SIM. However, this will stop me receiving calls on my UK number whilst out of the country.
Is there any way to keep both numbers working, without breaching the terms of use, and allowing incoming calls to each number on each SIM, when split between the two countries?
