Does the mobile provider make a big difference internet speeds?
Yes — and often a bigger difference than the router itself. While many mobile towers in the UK now host all major providers (EE, O2, Vodafone and Three) as part of shared‑infrastructure policies, that doesn’t mean all networks perform the same. In fact, even on the same physical mast, different providers can achieve very different speeds.

1️⃣ Each provider installs different hardware on the same tower
Even when sharing the physical structure, networks may use:
- Different antenna arrays
- Different backhaul capacity
- Different 4G/5G radio modules
- Older or newer hardware generations
This alone can cause huge differences in speed, upload performance, and signal stability, even though the tower location is identical.
2️⃣ Networks don’t always deploy the same technology at each site
One provider may have:
- 5G activated on that tower
- More LTE bands available
- Better carrier aggregation
- Wider bandwidth channels
Another might only run basic 4G on the same mast.
3️⃣ Local network congestion varies by provider
If everyone around you uses one provider heavily, that provider may perform poorly even if others are fast.
4️⃣ Your premises still plays a role
Building construction, layout, internal walls, metalwork, and window coatings can change how each network performs indoors.
Even though many towers now host all the major networks, the hardware, configuration, and technology each provider installs can be completely different, so performance often varies dramatically.
