Gamma Connect Alternative: FMC Without the Horizon Lock-in
Gamma Connect ties your FMC to Horizon PBX. IQ Mobile FMC works with any phone system — Asterisk, Broadsoft, 3CX, FreeSWITCH, and more. Same native dialler, better coverage on EE, from £15/month.
The PBX Lock-in Problem
Gamma Connect is a capable FMC product — native dialler, eSIM support, and solid functionality. But it has one critical limitation: it only works with Gamma's Horizon hosted PBX.
This means your FMC capability is tied to a specific phone system. If your business outgrows Horizon, if you want to move to a different platform, or if a customer doesn't use Horizon — you lose FMC entirely. You're locked in.
IQ Mobile FMC is completely PBX-agnostic. Our FMC SIMs work with any phone system. Switch PBX vendors without losing your FMC capability. It's FMC that adapts to your business, not the other way around.
