When a small firm in Manchester asked us whether a wholesale-led provider could match the flexibility of a broker, the answer boiled down to three practical questions: which network will give the strongest 5G signal in their area, how quickly can they talk to a real person when something goes wrong, and whether the contract will surprise them with hidden price rises.

Both Gamma and Compare The Networks sit behind the same four major UK carriers, EE, Vodafone, O2 and Three, but the way they reach the customer differs. Gamma sells its business mobile plans through a network of authorised partners. Those partners handle the sales call, the onboarding paperwork and the day-to-day support. The result can be a very personalised experience if you happen to work with a reseller who knows your industry, but it can also mean you are dependent on a third-party help desk that may not have the same level of training as the core provider.

Compare The Networks, by contrast, acts as a broker that pulls data from all four networks and presents a single, transparent quote. Because we own the relationship with the carriers, we can switch you from one network to another at the end of a contract without you needing to re-negotiate a new wholesale agreement. Our customers also get a single online portal where they can see usage, add lines and raise tickets. The portal is built for business users, so the language is plain and the navigation is straightforward.

Network choice

The biggest practical difference is how each service decides which radio access network you will use. Gamma's wholesale model often ties you to the network that the reseller has negotiated the best wholesale rate with. In many parts of the country that will be EE, because of its extensive 5G rollout, but in other regions you may end up on Vodafone or O2. The signal quality you experience therefore depends on the reseller's portfolio rather than your own assessment.

Compare The Networks evaluates the coverage maps for all four carriers and matches you to the strongest signal for each site you operate from. If you have offices in London, Birmingham and Newcastle, we can allocate lines on EE for the London site, Vodafone for Birmingham and O2 for Newcastle, all under one contract. The flexibility is built into the service, not left to the discretion of a reseller.

Account management

With Gamma you will usually have a dedicated account manager at the partner firm. That person can be very helpful if they understand the nuances of your sector, but the quality of that relationship varies widely. Some partners provide a 24-hour phone line, others only email support during business hours. Because the support is outsourced, any escalation has to pass through an additional layer before reaching the carrier's technical team.

Our approach at Compare The Networks is to give you a single point of contact, a senior account manager who can pull up any contract detail in seconds. All queries are logged in a shared ticketing system that you can access at any time. If a network outage occurs, we receive the alert directly from the carrier and can advise you on mitigation steps before you even notice the problem.

Inclusive international and roaming

International calling and roaming are often the hidden cost centres in business mobile contracts. Gamma's plans typically include a modest amount of EU minutes and a small data allowance for roaming, but the exact limits are set by the reseller and can change when the contract is renewed. If you have staff travelling to Africa or Asia, you will likely need to purchase additional add-ons.

Compare The Networks includes minutes to 39 countries and roaming on 83 networks as standard in most of our business packages. The roaming data is pooled across the whole account, so you do not have to manage individual line allowances. The rates are locked in for the duration of the contract, and any future price adjustments must be disclosed in pounds and pence, in line with the Ofcom rules that came into force in January 2025.

Contract approach

Legacy contracts signed before the 2025 regulation often contain percentage-linked price rises. Those clauses can be difficult to spot and can lead to unexpected increases when the carrier applies a CPI uplift. Gamma's contracts are usually fixed-term, but because they are negotiated through a partner, the fine print may contain clauses that are not highlighted in the initial quote. It is always worth asking the reseller to produce the full terms and to point out any early-termination fees or notice periods.

At Compare The Networks we provide contracts that are clear, with any price rise stated as a flat amount per line per month. We also offer flexible term lengths, 12, 24 or 36 months, and a "no-surprise" renewal process where you receive the new rates 30 days before the contract ends. If you decide to switch networks, we handle the migration at no extra cost.

How to decide which model fits your business

1. Assess your coverage needs, Use the coverage checker on the EE, Vodafone, O2 and Three websites to see which network gives the best 5G signal at each of your locations. If you need a mix, a broker that can blend networks may be the better choice.

2. Consider the support experience you expect, If you already have a trusted reseller who has helped you with other telecom services, staying with Gamma could feel familiar. If you have struggled with inconsistent help desk quality in the past, a single point of contact may save you time.

3. Check the international usage pattern, Look at your call logs from the past 12 months. If you regularly call outside the EU, a plan that bundles a wide roaming allowance will be more cost-effective than buying add-ons later.

4. Read the contract fine print, Ask for a copy of the full terms. Look for any percentage-linked escalation clause, early-termination fee and the length of the notice period. If anything is unclear, bring it to our attention and we will explain how it compares with the standard CTN contracts.

Side-by-side comparison

Real-world examples

A logistics company in Leeds moved from a Gamma reseller to Compare The Networks after a driver reported frequent loss of signal on the motorway. By analysing the coverage maps we switched the fleet's devices to a blend of EE and Vodafone, which lifted the 5G availability from 68 % to 92 % on the routes they travel most. The same company also saved around 15 % on roaming costs because the new contract covered the 39 countries they visit on a regular basis.

A boutique marketing agency that works with clients across the EU stayed with their Gamma partner because the reseller had a strong understanding of their billing cycles and offered a bespoke reporting dashboard. In that case the personal relationship outweighed the broader network flexibility, and the agency continues to benefit from the tailored support.

These stories illustrate that there is no one-size-fits-all answer. The right choice depends on how you weigh coverage, support and contract transparency. If you are unsure which factor matters most, we can run a quick audit of your current usage and show you a side-by-side cost comparison. It takes less than ten minutes and the result is a clear picture of potential savings.
