Three FAQs

Can I keep my mobile number?

Yes, this is called ‘porting’ your number and makes changing network a much smoother process.

Keeping your number means you won’t have to tell all your friends and family your new number or risk losing contact with anyone.

Your new network will guide you through the steps you need to take to port your mobile number

Can I upgrade to a handset plan from a Three SIM-only plan?

With a 30-day SIM-only plan, you have the freedom to upgrade or change your plan at any time, without worrying about exit fees or charges.

You can check the available upgrades by logging into My Three.

How long will it take for my SIM to arrive from Three?

Once your order is confirmed, your SIM will be delivered by standard post within 1-3 working days.

What are the advantages of SIM-only deals?

SIM-only plans are cheaper than deals that include a phone. So, if you’ve paid off your phone and are still happy with your handset, you’ll make a saving by switching to a SIM-only deal.

If you’re out of contract, you can also move to a SIM-only deal with your current provider, rather than rolling on your contract. Some networks will automatically move you to a plan-only price once your handset is paid off, so check with your provider.

SIM-only plans are also a good way to check how a new network performs without locking into a long term deal.

You could also decide to buy your phone outright, and then go for a SIM-only deal. It may work out cheaper than paying it back as part of your monthly mobile cost, but this will depend on your provider and the type of phone you plan to buy.

What do I need to switch to a Three SIM-only plan?

You can sign up to a Three SIM-only plan online. You’ll need your passport, drivers licence or EU National ID Card, as well as a €1 payment from your debit card.

Once you receive your SIM, you simply need to pop it into your phone. If you want to move your existing mobile number to Three, you just need to fill in the form on the Three website.

You may also need to contact your current mobile phone provider if you need to unlock your handset.

What is a SIM-only plan?

A SIM-only plan allows you to just pay for data, calls and texts. When you sign up you’ll get a SIM card with an allocation of data, texts and minutes, but the deal won’t include a phone.

SIM-only plans are generally cheaper and will save you money if you already have a phone you are happy with.
