Mijn ervaring
giffgaff is the most popular choice among indie developers who need a UK phone number. It runs on O2's network, so coverage and reliability are solid, and plans start at just £6/month.
The process is straightforward — order a SIM card online (they ship to freight forwarders), activate it when it arrives, and you've got a working UK number. I used giffgaff when setting up a UK LTD and it worked perfectly for verification calls.
If you only need a UK number occasionally, the £6/month pay-as-you-go plan is the cheapest way to keep one active.
