Which SIM Card do I need?

There are three different SIM card sizes: Standard also know as Mini, Micro and Nano. There are several ways to find the type of SIM Card your mobile phones uses; you can use our SIM Card Finder, look on the packaging your phone came in or the internet for specifications on your mobile phone.

What is a SIM only deal?

A SIM only deal offers a package of minutes, texts and data for a monthly cost, much the same as a traditional mobile phone contract. The difference, however, is that you don't get a new phone. This allows you to potentially reduce the cost of your monthly bill as your not paying for the new phone.

Will I be credit checked for a SIM deal?

If you are looking for a SIM only deal with your current network, they already have all your details so a credit check is highly unlikely.

You'll have to pass credit check if your looking for a monthly rolling contract or a 12 or 24 month SIM deal contract with another network. If you fail a credit check there are some great Pay As You Go SIM only deals on the market, the only possible disadvantage with this, is you have to regularly top up.

What are the benefits of SIM deals?

SIM Only deals are ideal if your happy with your current phone. A large percentage of your monthly bill will actually go towards the cost of the current phone.

As an example, you could get a SIM Only UNLIMITED Data plan for around £30 per month. If you wanted a UNLIMITED Data plan with a new phone it could cost over £80 per month.

If you take a 1 Month SIM Only deal, it also gives you the ability to change networks regularly to take advantage of any offers.

Should I choose a well know network?

Sometimes the lesser know names offer the best value for money. The lesser know networks use the bigger names networks, so the quality of the signal is no different, as an example GiffGaff and Tesco use the O2 network, Virgin uses the EE network.

Can I keep my current phone number?

Yes. You'll need to ask your current provider for a Porting Authorisation Code (PAC code). This can be done by calling them or sending them an email requesting your PAC Code.

Once you have your PAC code from your existing provider, you can call or email your new provider with the PAC code. The transfer of number is usually completed the next working day. So there is the possibility that you will not be able to use your phone for a day, whilst the transfer takes place.
