Hi, I've been I'd sim only customer with yourself last 9 yrs out of contract. I wanted to go with mobile.co.uk to take out unlimited usage for another 2yrs but will I be able to keep my existing number, it says on they're website to click here for existing customer sim upgrades so will my phone number be retained. Because what I've read is if I go with anyone else other than upgrading through this site that I will loose my number, and they're saying I would have to go to another network for a month then come back to I'd with a different email address to keep my existing number and set it back up again. Seems so confusing just to keep my existing number with the same network. Thanks
