Can I get a BT Mobile SIM if I have a bad credit rating?

Unfortunately, BT Mobile do not offer 1 month / 30 day SIM plans, which are ideal for those who have a bad credit rating.

BT Mobile only offer 12 month and 24 month SIM contracts. If you have a bad credit rating, you may find difficulty in being accepted for a long term contract.

We compare a range of SIM Only deals from other networks, many of which offer 1 month / 30 day rolling plans for those with a bad credit rating.

Do I need to unlock my phone to use a BT Mobile SIM?

If you bought your phone from BT Mobile, or it originally came with a BT Mobile SIM, then you shouldn’t need to unlock your phone in order to use a BT Mobile SIM.

Since December 2021, it is illegal for any network to sell a mobile phone that is locked to a specific network.

If you bought your phone before this date, it may be locked to your current network. If you’re unsure if your phone is unlocked, simply insert a SIM from a different network - if your phone is locked, an error message will be shown.

All providers must unlock your phone for free. You will need to contact your current network to do this. They will ask for your IMEI number, which you can obtain by dialling *#06# from your phone.

What size SIM cards can I get with BT Mobile?

BT Mobile offer all SIM card sizes. You will be sent a standard SIM card size, which will have cutouts that can be broken down to a micro SIM or nano SIM. You can request an eSIM from BT Mobile if you have a phone which supports the technology.

  1. Standard - the largest SIM card size, which is generally used with older non-smartphones. Newer phones are likely to use micro or nano SIMs.

  2. Micro - Once considered a smaller replacement for standard SIMs, micro SIMs are less prevalent today, being replaced by the even smaller nano SIM. Older smartphones or budget phones may still use a micro SIM.

  3. Nano - The smallest and most common SIM card size used in phones sold today. Used by the newer iPhones and Samsungs.

Can I switch from my current network to a BT Mobile SIM?

Yes, it’s easy to switch to BT Mobile. From your current network, text PAC to 65075 for free. You will receive a reply text within 5 minutes, which will contain your PAC code.

You will need to give this PAC code to BT Mobile. You can do this at the time of purchase, or by contacting BT after you have received your BT Mobile SIM card.

After you have given your PAC code to BT Mobile, they will begin the switch or your behalf, which normally takes 3 working days. Once the switch has completed, you will lose signal with your current network. When this happens, you can insert your BT Mobile SIM to complete the switching process.

For more information, see transferring your phone number to a new network.

Does BT Mobile have good coverage?

By entering your postcode into the BT Mobile coverage checker, you will be able to see the type of signal you will receive and the estimated signal strength.
