- Changing mobile network? If you’re keeping the same phone but changing to another network, it might be necessary to first unlock your handset. We’ve got a step-by-step guide on unlocking an iPhone and unlocking a Samsung Galaxy handset.
- Coverage is identical on many mobile networks. Many networks share the same coverage provider: you’ll get identical levels of coverage when using any of these networks. To give an example, ASDA Mobile uses coverage from EE and giffgaff uses coverage from O2.
- Keeping your mobile number. If you’re changing mobile networks, it’s super easy to keep your current phone number. Once you’ve ordered your new SIM card, contact your current network and ask them for a PAC Code. You can then pass this on to your new mobile network and your phone number will be moved over on the next working day. For more information, see our guide to transferring your mobile phone number.
