5 best international SIM-only deals in January 2018

Monday, December 18th 2017

'International' refers to a call make from the UK to elsewhere in the world, as opposed to 'roaming' which is making a call while you are out of the UK. Some providers offer special bolt-ons for making international calls, whereas others simply offer cheap rates.

Here is our pick of the best five SIM-only deals if you make a lot of calls abroad.
