iPhone 6 - using temporary UK sim card
I have a US Verizon iPhone 6 and travel to the UK for about 3 months a year. In the past, I've carried a separate UK mobile flip phone with a Vodafone sim card. I'd prefer to use my iPhone 6, but with the UK sim card number. If I get a Vodafone or BT (nano) sim card, will it work with my Verizon iPhone - and then replace the Verizon sim when I return?
