You might have questions about pay monthly SIM deals so we’ve tried to answer as many as possible below:

Why choose a SIM only deal?

If you’ve finished paying off the finance on your mobile phone, one option is to take out another contract and get yourself a brand new phone. However, for many people, that’s not necessary as the phone they currently own has plenty of life left in it. Replacing the SIM card in your phone can be a great way to reduce your monthly outgoings or to increase the amount of text, minutes or data you’ll be entitled to each month.

How long are you tied into SIM only contracts?

The great thing about pay monthly SIM deals is that you can choose how long you are tied into them. Many SIM contracts are only 1-month deals which means you’re free to change your provider or deal as often as you like. Longer-term contracts of 1-year, 18-months or 2-years are usually a bit cheaper per month and make budgeting a little easier.

What SIM card do I need?

You needn’t worry about what SIM card your phone takes because when you order a SIM only deal, you’ll be sent a multi-SIM card. It will contain a nano SIM, micro SIM and standard SIM card so will fit most makes and models of mobile phone.

What networks offer Pay Monthly SIMS?

Can I keep my old phone number on a SIM only deal?

One of the great things about SIM only deals is that it’s now really easy to transfer your old phone number to your new SIM. Recent changes mean that you don’t have to call your old provider to ask for your number to be moved. Instead, you just need to send a text message and you’ll receive a release code for your new SIM provider in a matter of minutes. There’s more information on the OFGEM website.

Isn’t SIM only the same as a Pay As You Go (PAYG) deal?

No. SIM only deals will always come with a monthly allowance for calls, texts and data usage. PAYG sim cards don’t usually come with an allowance which means every call or text you make will mean the credit on your account will reduce. Usually, PAYG call rates are higher than on SIM only deals.
