Why is Uswitch cheaper then Three website?

[B&W]

I've been with 3 for donkeys now, was thinking of getting a new contract with a new phone. I was looking at the S10+ and for me (apparently special customer if u login via the 3 app) it costs £49 a month plus £79 upfront. 30gb plus unlimited calls/text (or unlimited data for same price)

Now, if I go via uswitch it costs £39 per month and £29 upfront. 100gb data, unlimited calls/texts.

I know I can get the uswitch deal then cancel my current sim only and change the PAC over but I dont want to as I dont want to miss any calls as this number is used for business.

Very annoying.

Just call Three and tell them about the uSwitch deal, they matched it when I did it for my dad recently.

Tried a while ago, "this service is now closed" limited bla bla bla. I'l try tomorrow via there app.

Been on the phone with them for 40 minutes and he keeps giving me "special offers" which is the same as the website standard deal....

I don't think he actually understands any English, he can just speak it like a parrot.

5 more minutes and I'll cut it off and try there chat thing via the app..

After 1 hour and 8 minutes on the phone he finally managed to match the uSwitch offer...
