I bought a PAYG dongle + 3G router from Vodafone in Spain while on holiday and got it working OK there. Now I'd like to get them both working in the UK. Models are Huawei K3765 dongle and ZTE MF10 router.
Is this possible, and how hard is it to sort out?
I would get a UK SIM, but does that mean buying a new dongle? If I do get a new dongle, can I at least re-use the router?
