This is quite a complicated process so only do it if you have the patience!
Because you're taking out a contract, there will be a credit check done. This is really not a big deal but if you don't want to go through it then don't go ahead with this deal. Otherwise it's fair game.
How to get a Huawei P20 Pro for £245...
- Click Buy Now
- Click on "See our plans"
- Go with the 5GB data plan with £245 upfront payment or £31 per month one
- Pay your first month to claim a free gift
Once you get your P20 Pro phone, call up O2 from your existing number or from your new O2 number within 14 days and cancel the talktime part of the deal. Don't leave it more than 14 days or else you'll get charged your first month. You can only get the free gift if you pay your first month of £31.
Sometimes the O2 agent won't know what you're trying to do - just hang up and try another agent because someone will eventually understand and sort it out for you.
If you want to move from O2 just ask them for a PAC code and move your number to a pay-as-you-go SIM.
