Best T-Mobile SIM Only Deals

For customers who already have a phone that they’re happy with, T-Mobile offer a range of SIM Only contracts. These contracts are generally cheaper than equivalent deals which include a phone, because the cost of a handset is not represented in the monthly charges. SIM Only deals are also available with short contract durations, offering greater flexibility.

SIM Only deals from T-Mobile are available either as 30 day rolling plans or 12 month contracts. All SIM Only tariffs include 5000 free texts and a combination of T-Mobile minutes and any-network minutes. T-Mobile also offer their ´Full Monty´ deal, which includes unlimited minutes, text and data, as a 12 month SIM Only contract

Most T-Mobile SIM Only contracts do not include a data allowance as standard, but this can be added through a Booster for a fixed monthly fee. See data allowance for full details.

BlackBerry and Micro SIMs are also available from T-Mobile on the same tariffs as their standard SIM Only deals.

• Select and purchase your new SIM Only tariff from T-Mobile. They will assign a new phone number to you.
• Contact your current network and ask for a ‘PAC’, which means ‘Porting Authorisation Code’. Your network should provide this either over the phone or in a text message.
• Pass on your PAC to T-Mobile along with your contract details.
• The transfer should take a few working days to complete after this

See network contact details.

T-Mobile SIM Only customers can select a mobile data allowance when they sign up to a new deal. There are three options available, each offering a different monthly data allowance to suit different users: Basic Internet, Standard Internet and Extra Internet.

T-Mobile does not charge customers who go over their allowances extra, but their usage may be restricted. SIM Only customers without an internet Booster can still access the web through T-Mobile’s network and are charged per day.
