Are you thinking of switching your mobile provider? You’re not alone. With such a wide range of options available right now, so many mobile users are searching for a better deal. Here at Roams we want to make it easier for you to make that decision with confidence.

This article will answer some of the most frequently asked questions about mobile networks, coverage, sim-cards and plans. So, without further ado, let’s jump into it!

Can I switch my mobile provider?

This is the most fundamental question you must ask yourself before you set out to switch your network. It is important to remember that if you are in a contract with a provider, it may be more complicated than you think to switch or cancel your current deal. Have a look at any emails or documents regarding your contract, or simply ring up your provider and ask them when your contract is due to expire, and the terms of this contract.

If you are on a rolling-contract SIM-only deal, you need to give your network 30 days’ notice before switching. If your contract is a year or two long, you may have to pay for the remaining months of your contract up front, which may prove to be expensive if you want to switch right away with many months left on the current contract.

The best thing to do is have a chat with your mobile network, get some information on your contract and what would happen if you were to switch. You never know, if the network wants to keep you as a customer they may offer you a better deal!

What steps do I have to follow?

Once you have figured out the terms of your current contract and how to cancel it, the next step is checking out coverage.

Whichever network you choose, you need to ensure it can provide good coverage to your area. You can find so many great coverage comparison tools in one Google search, so have a look at our best mobile coverage guide to get a good overview!

How can I keep my number when switching providers?

It’s a pain to have to tell all your contacts that you have a new number, and then comes the tasks of learning your new number off by heart! Thankfully, keeping your current number is very simple.

All you need is a PAC code (Porting Authorisation Code), which your current provider can give you in store or via customer services online or on the phone.

This PAC Code will allow you to switch your number by simply providing it to your new chosen provider.

Make sure you use it within 30 days. After this 30-day period, it runs out, and you'll need to text or call your network and ask for another one.

Here’s a table listing the major network providers and their contact information to get your PAC Code:

How can I keep my old phone and get a new deal?

Holding on to your current mobile is becoming more and more popular as many consumers reject the fast turnovers of new mobile models and choose to keep using their trusty models that still work. If this sounds good to you, we have some great news! By choosing a sim-only deal, you aren’t locked into a yearly contract.

One-month SIM deals can be cancelled with just 30 days' notice. So, you can change your mind as many times as you want and get a new phone if your current one dies, or even if you just fancy an upgrade.
