Upgrade to sim only

[Anonymous]

My contract is due up and I'm looking to go to sim only contract. When I was ordering online it was coming up it was going to send me out a new sim, does that mean my number will change? Also how do I find out my usage so I get the right tariff?

You don't need to change sim if you are keeping your phone, the contract will just change. You only need to use the sim if changing phone and the sim size is different.

Hi

No your number won't change.

Just carry on using your current SIM card.

The changes happen in your account.

They send out a sim now as there all nano sized SIM cards with adapters incase you change phones which take a different sized sim and the new ones are 4G versions.

If you do need to use a new sim, for any reason, you can use this form to keep your original number

It may be an idea to check if your existing sim card is a 4G enabled. It would be an issue if your phone and tariff are 4G.

I had the same concern recently, and the above has answered most of my queries except one!

I am currently on simplicity 30 day contract and wish to change to a new simplicity 30 day contract, but at what point would my contract change? At the end of the current 30 day period, instantly and I get charged for the current 30 day period and the new 30 day period or instantly and I get charged a pro rata amount for the current 30 day period and in full for the new 30 day period?
