When your Wavenet contract comes up for renewal, the first thing most of our clients ask is whether there is a better network for their needs. The answer is rarely a simple yes or no, it depends on coverage, the way you manage accounts, the value you place on international calling and how flexible the contract terms are. In this guide we walk through the five most common alternatives that sit behind the Compare The Networks (CTN) platform, O2 Business, EE Business, Vodafone Business and Three, and highlight what each is good for, as well as the key questions to ask before you switch.
Why the focus on alternatives? Wavenet grew largely through acquisition, which means the service experience can vary widely from one customer to the next. Some businesses love the personalised support they receive, while others report that the transition from a legacy brand to a new operating model feels disjointed. That variance is not unique to Wavenet; any provider that has merged several brands can have growing pains. The safest way to protect your business is to compare the core network strengths and contract features of the main players before you sign a new deal.
What to look for in a business mobile provider
- Network coverage and 5G availability, If your team works across the UK, you need a network that reaches both urban centres and remote locations. EE boasts the widest 5G footprint, while Vodafone and Three now share the same infrastructure after their recent merger, giving them a comparable reach in many areas. O2 and the CTN-managed O2 Business plan focus on strong 4G performance and are expanding 5G steadily.
- Account management tools, Large enterprises often need a portal where they can add or remove lines, set usage limits and access detailed billing. EE Business and Vodafone Business both offer robust dashboards that integrate with common accounting software. CTN's own platform gives a single pane of glass for all four networks, which can simplify management for mixed-fleet environments.
- Inclusive international calling, For businesses that call abroad, the number of minutes and the list of covered countries matter. CTN's standard business bundles include calls to 39 countries and roaming across 83, a benefit that is reflected across the provider options we discuss.
- Contract flexibility, Since Ofcom now requires any price rise to be stated in pounds and pence, many legacy contracts still carry percentage-linked clauses. Look for providers that offer clear, fixed-price renewal terms and the ability to adjust the contract length without hefty penalties.
- Customer support reputation, While we cannot quote exact complaint figures, it is worth checking recent reviews and asking for a dedicated account manager. A provider that can respond quickly to SIM swaps, device upgrades or billing queries will save you time and stress.
Below is a quick side-by-side comparison of the five options we cover. The table focuses on the elements that matter most to UK businesses at the point of renewal.
| Provider | Network Coverage | Business Account Management | Inclusive International Calls | Contract Flexibility |
|---|---|---|---|---|
| CTN (O2 Business) | Strong 4G, expanding 5G, good urban coverage | Dedicated portal, integrates with Xero and Sage | Calls to 39 countries, roaming in 83 | Fixed-price contracts, 12-month minimums |
| EE Business | Widest 5G reach, solid rural performance | Advanced dashboard, API access for large fleets | Calls to 39 countries, roaming in 83 | Clear renewal price, early-termination fee disclosed |
| Vodafone Business | Nationwide 5G via shared Vodafone-Three network | Comprehensive portal, multi-user access | Calls to 39 countries, roaming in 83 | Fixed-price options, flexible month-to-month upgrades |
| Three Business | Good 5G in cities, improving outside | Simple online portal, suitable for SMEs | Calls to 39 countries, roaming in 83 | Month-to-month contracts, transparent price changes |
| CTN (direct) | Leverages all four networks, picks best signal per location | Single-view dashboard for mixed-network fleets | Calls to 39 countries, roaming in 83 | Custom contract lengths, no hidden percentage rises |
O2 Business, The reliable workhorse
O2 Business is a solid choice for companies that value consistency and a straightforward pricing structure. The network delivers strong 4G performance and is steadily rolling out 5G, particularly in major conurbations. If your staff are based mainly in cities like London, Manchester or Birmingham, O2's coverage will feel robust. The O2 Business portal lets you allocate lines, set data caps and monitor usage in real time, which is handy for organisations that need to keep spend under control.
What O2 does well is its focus on customer service. Many of our clients tell us that the support team is quick to respond, and the provider offers a dedicated business line for queries. However, if you need the absolute widest 5G footprint, EE still leads the market. O2's contract terms are generally clear, but it is worth confirming whether your renewal clause includes any percentage-linked price increase, especially if your original agreement predates the 2025 Ofcom rule change.
EE Business, The 5G champion
EE Business remains the go-to for organisations that cannot compromise on speed or coverage. With the most extensive 5G network in the UK, EE can deliver gigabit-class speeds in many city centres and a solid 4G signal in rural areas. The business portal is feature-rich, offering API access for large fleets, automated device provisioning and deep analytics that integrate with ERP systems.
The trade-off is that EE's pricing can be slightly higher than some of the other options, particularly for smaller contracts. That said, the value you receive in terms of network reliability and the ability to future-proof your mobile strategy often justifies the cost. When you review your contract, ask for a clear breakdown of any early-termination fees and verify that the renewal price is fixed for the term you choose.
Vodafone Business, The balanced option
Vodafone Business benefits from the recent merger with Three, meaning the combined network now rivals EE's 5G reach while offering competitive pricing. The provider's portal is intuitive and supports multi-user access, making it easy for IT teams to manage large numbers of lines. Vodafone also provides a range of device financing options, which can be useful if you need to roll out new smartphones across the workforce.
A notable strength is Vodafone's international calling package, which aligns with the CTN standard of 39 destination countries. For businesses that travel frequently across Europe, this can translate into significant savings. As always, double-check any renewal clauses for hidden percentage increases, and ask about the process for moving from a legacy contract into the newer, fixed-price framework.
Three Business, The agile SME solution
Three Business is often praised for its simplicity and flexibility. The provider's 5G coverage is strongest in densely populated areas, and its 4G network remains reliable elsewhere. The online portal is straightforward, allowing small to medium-size enterprises to add or remove lines without needing a dedicated account manager. Three also offers month-to-month contracts, which can be attractive if you prefer not to lock in for a full year.
Because Three's network is now part of the same infrastructure as Vodafone, you gain the advantage of a broad 5G footprint without paying a premium. The main consideration is that the coverage outside major cities may not be as deep as EE's, so it is worth testing signal strength at your key locations before committing. As with any provider, confirm that the contract you are offered does not contain any percentage-linked price rise clauses.
CTN, The one-stop shop for mixed-network fleets
At Compare The Networks we partner with all four major carriers, meaning we can assemble a bespoke package that pulls the strongest signal from each network depending on where your employees are located. This approach is especially useful for businesses with a national footprint that experience variable coverage. Our own portal gives you a single view of usage, billing and contract terms across the entire fleet, simplifying administration.
Because we negotiate directly with the carriers, we can often secure fixed-price contracts that comply with the latest Ofcom rules, removing the risk of surprise hikes. When you speak with us, we will ask about any existing Wavenet agreements you hold, verify the renewal terms and map out a migration plan that minimises downtime.
Checklist before you switch at renewal
- Review your current contract, Locate the clause that governs price increases and renewal notice periods. If the contract predates January 2025, it may still contain percentage-linked rises.
- Test coverage, Use a coverage checker or ask us to run a signal audit at your key sites. This will reveal whether a provider's network truly meets your needs.
- Compare total cost of ownership, Look beyond the monthly line price. Include device financing, international minutes, data overage charges and any administrative fees.
- Assess support levels, Ask for a dedicated account manager and confirm the SLA for issue resolution. A fast response can be worth more than a few pounds saved per month.
- Plan the migration, Determine how many SIMs need to be swapped, whether devices will be upgraded and how you will handle numbers porting. A well-planned rollout reduces disruption.
- Check for hidden fees, Early-termination penalties, SIM replacement charges and contract amendment fees can add up. Get these in writing before you sign.
If you follow this checklist, you will have a clear picture of whether staying with Wavenet makes sense or if one of the alternatives offers a better fit for your business.
