Are you happy with your current phone and not keen to upgrade? You’re in the right place! Over the past few months, I’ve been testing several network providers here in the UK in an effort to find a network that matched my needs and I think I finally found one!

For those who live outside of the UK, your options may be different but here in the UK, we have pay monthly contracts that come with a phone, these usually last from 12 months to 3 years depending on the offer and the provider. We also have an option to go Sim-only and there are a few options.

Depending on the deal you decide to go with, sim-free has the option of 1-month rolling contracts which you can cancel providing you with the option to move to another provider should you need to. This is a good option for when you see a better deal you like with another provider.

I wanted to start by talking about the factors that will help you pick the right provider. This is a very important part as just because the deal is good doesn’t mean the rest of the service will be suitable for your needs.


Here in the UK, we have four main providers, EE, 3, Vodafone and o2. Other providers do exist such as the supermarket network Tesco Mobile or Smarty, VOXI and GiffGaff, there are more but I didn’t want to make the…
