How do I go about upgrading via Mobiles.co.uk?

Can I keep the phone I currently have?

If you’re happy with your existing phone, but want a different tariff, your best option is to upgrade to a SIM only deal. Browse our O2 SIM only deals right here.

Do I receive a new SIM card with an upgrade order?

If you order a new handset for your upgrade, there’s a chance that your new phone may need a different sized SIM. As part of your order, we’ll send you an O2 multi-SIM which can be broken down to fit any SIM slot, from iPhones to Android devices.

I’m on a SIM only tariff. Can I upgrade to a handset deal?

The term ‘upgrading’ really just refers to the process of continuing your current connection. Therefore if you want to move from SIM-only to handset, or vice-versa, it’s simple to do so. Just be aware that a handset contract is likely to incur a higher monthly bill than SIM only.

Can I keep the phone I currently have?

O2 upgrade contracts offer all the same benefits as new O2 contracts. These include Priority Rewards and Tickets, offering you monthly treats and priority event booking. For a complete look at the perks of O2, take a look at our O2 blog.

When am I able to upgrade with O2?

O2 allow you to upgrade 30 days before the end of your contract. You can check the exact time of your upgrade eligibility by logging into your O2 user account, either online or through the O2 app.

Can I upgrade early with O2?

Yes, with O2 you can upgrade up to 30 days before your contract is due to end. Log into your O2 account to learn your exact upgrade eligibility date. Alternatively, you can upgrade before your eligibility date, but this will incur a termination fee equivalent to your remaining line rental.
