You can find all of the information you need on the C Mobile tariff price on our Tariff page. This will outline our low cost tariff, our international and roaming rates and our half price C Mobile to C Mobile tariff.

Once you have received and activated your C Mobile SIM, simply call your existing network provider and ask them for a PAC (Port Authorisation Code). It may take them a day or two but once you have the code, just give us a call with the number and we will sort the rest. Why not take advantage of 'My C Mobile' online? We suggest you register with your new C Mobile number before starting the porting process. For more information on keeping your old number click here.

Because we’ve teamed up with our network partner Orange, you get all of the great benefits of the excellent Orange coverage. To check your local area, just enter your postcode in to the coverage checker here.

Place the SIM into the phone and make a call - It really is that simple! The first call you make will be diverted to our activation service and you will hear a pre-recorded message. The activation process will just take a couple of minutes to complete and then your C Mobile SIM is ready to use.

Not at all. We offer SIM only deals, so that the life of an old handset can be extended and no unnecessary waste is caused. Just place the C Mobile SIM in to your old phone and make a first call to activate it. In some cases, your phone may be locked to another network. If this is the case, you will need to unlock your phone before you can use it with your C Mobile SIM. See the ‘How do I unlock my phone?’ question for more information.

You will get a double top up only the first time that you top up online at the C Mobile website. First you will need to create an account with C Mobile. When you top up online for the first time using a debit or credit card, you can top up £10 or £20. C Mobile will double your credit on that first top up. So, if you top up £10, we will add £20 credit to your SIM. It’s our way of saying a big 'thank you'!

You can top up your C Mobile SIM online, by registering here at the C Mobile site. For more information on topping up click here.

Mais oui. You can use your mobile when you are outside of the UK, but you should be aware the cost of making and receiving calls will be different from the UK and changes will vary, depending on where in the world. For more information on call charges, when abroad, click here.

Just call 555 from your mobile phone and follow the instructions. Why not record a personal message and setup other options? It couldn't be easier!

Call 1260 from your mobile phone, or simply login to the My C Mobile section of this website to find your latest balance.

Of course. Just register your SIM and create an online account. You can create your account here. Please provide your SIM number and mobile phone number. From the account section you can check your balance, top up using a credit or debit card, or redeem a voucher code.

You do not need to register a card to top up with C Mobile. Each time you wish to top up, you can enter your card details in full, rather than registering the card.

Voucher Top Ups will be coming soon to C Mobile! The best way to top up at the moment is online, using My C Mobile.

Please let us know so that we can put a stop on the SIM. You will be liable for any calls made on the phone until that point. We will also give you your phones IMEI (identification) number, which you should pass on to the police when reporting the theft. If it happens to you, call us immediately on 01327 306477 and we'll do our best to help you out in a difficult situation.

We can blacklist your phone so it will be unusable - our network can recognise if a phone has been reported lost or stolen. We'll send you a replacement SIM card when you are ready to resume your service.

If you're happy with your existing mobile phone and have bought a C Mobile SIM only pack, your phone screen may show the following when you insert your new C Mobile SIM in your phone:
'Blocked', 'barred', 'incorrect SIM' or 'SP lock'.

This means your mobile phone is currently locked to another network and will need unlocking before you can use your new C Mobile SIM. To do this, call your current network provider to unlock it for you. You may have to give notice and they may charge you for this.

That’s ok, it happens to the best of us! On the login screen you will see that you can request an email if you have forgotten your password. We will reset the password for you and send a new password via email.

We have added a few extra contacts to your C Mobile SIM that you might find useful. You can now quickly find out your balance, call your voicemail or call the Customer Care team by calling the correct contact from your contact list.

We have also added some useful 'eco friendly' contacts that you might like to try out. Give them a go to see if you can make your world that little bit greener!

To redeem the £5 airtime that you purchased with the SIM, you will need to go through the SIM register and redemption process here. You will need your SIM number and mobile number to hand. You can then create a My C Mobile account, which will allow you to quickly top up online and check your balance.
