Tips to Find the Best Network for Phone Contracts

What’s the UK’s best network for phone contract deals?

That’s a hard question to answer with so many options to choose from.

But fear not! The Mega Mobile Deals team has created the following contract phone guide to help you find the best network for a phone contract.


O2 is one of the longest-standing mobile networks in the UK, and known for its high standard of customer rewards (thanks to Priority Moments). The vast majority of users have access to 4G too.


Three boasts an impressive international roaming program (Go Roam) which enables users to roam in 49 locations across Europe at no extra cost. International roaming is available in 89 countries for £5 a day via Go Roam Around the World. Handy for regular travelers.


EE is classed as the fastest 4G network in the UK, bringing it to more locations than any other (even O2). 4G+ is accessible to customers on EE Max schemes, restricted to London and other big cities. 5G is also available for users with compatible devices.


This is considered the best for voice calls across Birmingham, London, Bristol, and other major cities. Wi-Fi calling is available too, enabling users to enjoy voice calls even with no mobile signal. There’s also the VeryMe app for rewards.


giffgaff is a popular choice, named Network of the Year in 2018 by Uswitch. This is a virtual network which runs on O2, and offers cost-effective SIM-only contract deals for customers on a tight budget.


Plusnet leverages EE’s 4G network to bring fast data to 99 percent of the UK. The Roam Like at Home plan lets you use your standard monthly allowance in 40+ countries across the EU. Smart caps prevent users from exceeding a certain price limit, which is great if you have a poor credit history and want to avoid debt.

Virgin Mobile

Virgin Mobile utilizes EE’s network for fast 4G coverage and adds unused data from one month to the next to avoid waste. Messaging across Facebook Messenger, Twitter, and WhatsApp doesn’t count towards data usage.

BT Mobile

One of the big highlights of BT Mobile is the free BT Sport app, which gives customers access to Premier League games live. This is free for three months on 500MB – 3GB deals or free for life with 15GB contracts. Data, call, and text allowances apply in 47 countries worldwide.

iD Mobile

This network offers monthly caps to avoid exceeding a limit and unused data rolls over automatically. Wi-Fi calling is available too.


Smarty is a great network for bad credit card holders, as there are no credit checks. It offers SIM-only UK contract phone deals, incredibly low prices, and pays users back for unused data. Contracts roll over month to month.

Tesco Mobile

Cap monthly spending with Tesco Mobile and upgrade to a new phone at any time with Anytime Upgrade Flex.

Lebara Mobile

This network’s SIM-only deals include usage caps and there are no credit checks. It’s another solid option for bad credit score phones.


Customers can cap data to avoid unexpected charges. All SIM only contracts offer unlimited texts and calls.

Sky Mobile

Users with existing Sky accounts can stream Sky TV and access Sky Apps at any time without devouring data. All unused data rolls over.


Voxi is aimed at younger customers with its 30-day SIM-only contracts. Social media or messaging apps can be used without affecting data allowances.
