Should I switch my Gamma reseller or Gamma itself?

Often the reseller is the problem, not Gamma wholesale. For larger accounts, changing reseller partner while keeping Gamma underlying service is possible. For smaller accounts, switching wholesale service entirely (to direct network or CTN) is usually simpler.

Alternatives to Gamma Business Mobile (2026): Honest Options

Last updated: April 2026

Gamma is a major UK telecoms wholesaler — more B2B channel-facing than direct-to-customer. You probably get Gamma services through a reseller partner rather than buying direct. If you're looking for UK business mobile alternatives, the landscape looks slightly different.

Understanding Gamma's model

Gamma's Horizon (VoIP) and Gamma mobile services are generally sold through:

IT support companies reselling Gamma as part of wider IT bundles
Telecoms resellers using Gamma wholesale for VoIP
Some direct enterprise customers

So your experience depends heavily on which reseller partner sold you Gamma services, not just Gamma itself.

If your issue is with Gamma's underlying service, alternatives involve switching technology (different wholesale provider). If your issue is with your reseller, you can sometimes keep Gamma and change reseller.

If your main issue is the reseller partner

Most Gamma-branded complaints we hear are really reseller-partner issues:

Account management responsiveness
Billing complexity
Upsell pressure
Support escalation
Contract terms

If that's you, the question isn't "alternatives to Gamma" — it's "alternatives to [my reseller partner]". You might be able to:

Change Gamma reseller while keeping Gamma wholesale service — less common but possible for larger customers
Switch to a different wholesale with a different reseller
Go direct to a network-owner (EE, Vodafone, O2 Business, Three Business)
Use a specialist business mobile reseller (CTN, others)

If your issue is with Gamma's mobile service itself

Gamma Mobile operates via Vodafone's network. If coverage or features are the issue, alternatives:

CTN

Across EE, Vodafone, O2, Three — whichever network suits your coverage best. Inclusive 39-country calls and 83-country roaming. UK-based account management.

O2 Business direct

Roam at Home on most plans. Direct from network; no reseller in between.

EE Business direct

Best UK rural coverage. Daily roaming fees unless on specific inclusive plan.

Three Business direct

Cheapest unlimited data of the four networks. Coverage improving.

The VoIP angle (if you came to Gamma for Horizon)

If you're using Gamma primarily for VoIP (Horizon), switching business mobile alone doesn't affect your VoIP. You can keep Horizon while moving mobile. Worth separating the decisions.

For VoIP alternatives specifically (different conversation from mobile), consider:

Microsoft Teams Phone
8x8, RingCentral
BT Cloud Voice
CTN VoIP (we partner with various cloud VoIP platforms)

Questions to ask before switching

If you're considering leaving Gamma (or your Gamma reseller):

Who is the underlying network? Some "business mobile specialists" resell the same wholesale you already have.
What specifically is broken? Clarify if it's the service or the support.
What's the ETF? Across both Gamma wholesale contract and any reseller contract on top.
Can you unbundle? If Gamma is part of a bundled deal with VoIP or broadband, unbundling may be restricted.
Who's my new named contact? Make sure the alternative has better account management, not just different.

FAQs

Is Gamma a UK mobile network?

No. Gamma is a UK telecoms wholesaler — it doesn't own network infrastructure in the way EE, Vodafone, O2 and Three do. Gamma Mobile uses Vodafone's underlying network via a wholesale agreement. For coverage purposes, Gamma Mobile = Vodafone coverage.

Can I keep Gamma VoIP but change my business mobile provider?

Usually yes — VoIP and mobile are separate services contractually even if bundled through one reseller. Check your specific contract for bundling clauses and any partial-termination fees.

What's the best UK business mobile alternative to Gamma?

Depends on why you're leaving. For cheaper: Three Business. For better EU roaming: CTN or O2 Business. For stronger UK coverage: EE Business. For enterprise integration: Vodafone Business. For named UK account management: CTN.

Should I switch my reseller rather than Gamma itself?

Often yes — if your complaints are really about the reseller partner (account management, billing, support), switching reseller while staying on Gamma wholesale may be simpler than switching underlying service. Not always possible with smaller customers; more common for larger accounts.

Does CTN resell Gamma services?

No. CTN works with the four UK mobile networks directly (EE, Vodafone, O2, Three). We don't resell Gamma.
