SIM Only Upgrades

When can I upgrade?

When can I upgrade?

You can upgrade your contract when you come to the end of your current network agreement, although if you’re with Vodafone, you have the option upgrading 75 days early. If you’re usure, be sure to check out our Upgrade Checker for further help. It’s also worth remembering that you don’t need to have purchased from Mobiles.co.uk to upgrade with us.

If you wish to upgrade earlier than your eligibility date, you’ll need to cover the cost of your remaining line rental, which is paid to your network as an early upgrade fee.

Why choose a SIM only upgrade?

Why choose a SIM only upgrade?

Upgrading your contract doesn’t mean you need to order a more expensive handset. In fact, you can upgrade without ordering a new phone at all, by selecting a SIM only upgrade. If you’re still happy with your current phone, why not upgrade to a SIM only, to enjoy lower monthly costs?

Another perk of buying a SIM only upgrade deal is the option to select shorter agreements, such as rolling-monthly and 12-month contracts. You can still expect the usual monthly perks such as Vodafone’s VeryMe rewards, and Rollover Data on iD Mobile.

FAQS

Who are SIM only upgrades best for?

If you’re happy with your current phone, and you simply want to pay less for your monthly plan, then upgrading to a SIM only deal could be the best option for you. As SIM only upgrade contracts have the choice of shorter agreements, it’s also a great option if you want to wait for an upcoming handset that’s not yet been released.

Do I get a new phone with a SIM only upgrade?

No, you’ll just receive a new SIM, which you can pair with an existing handset. If you’re happy with your current phone, simply swich SIMs once your new order has arrived and been activated.

What size SIM do I need when I upgrade?

You may be concerned as different handsets can require different SIM card sizes, however there’s no need to worry. All SIM cards ordered from Mobiles.co.uk are supplied as combination SIMs (sometimes called multi-SIMs). These are made of perforated plastic, and can be snapped down to the required size for any phone. These are made of perforated plastic, and can be snapped down to the required size for any phone. We also offer the option to upgrade via e-SIM if you have a compatible handset.

Which network can I upgrade on?

We offer SIM only upgrade deals on Vodafone and iD Mobile, and you don’t need to have placed your previous order with Mobiles.co.uk in order to upgrade with us. If you’re on a different network to the ones mentioned, you can also save money by switching networks. Simply request your network PAC and apply this to any of our regular SIM-only deals.

Can I upgrade from a phone contract to SIM only?

Absolutely. Although the term ‘upgrade’ is generally used, you can renew your network agreement with a new phone of higher or lower value, or simply as a SIM-only upgrade. Just decide on how much you’d prefer to spend on your monthly bills, and if you’d like to reduce your payments, a SIM-only upgrade could be the right option for you.

Will I keep my number with a SIM only upgrade?

Yes, one of the main benefits of upgrading is that you get a new contract which automatically carries over your existing number. There’s no need to worry about PAC codes or porting, just choose one of our best SIM only upgrade deals, and let us know your current number when prompted during the checkout process. We’ll arrange the rest.
