Enabling Lyca Mobile 5G on iPhone

Confirm your iPhone supports 5G
Not all iPhone models include a 5G modem. Check your device's official spec sheet for '5G NR' or 'Sub-6GHz 5G'. If 5G is absent from the spec, the device cannot connect to Lyca Mobile 5G.
Check your Lyca Mobile plan includes 5G
Log into the Lyca Mobile app and verify your current plan includes 5G access. {c_5g}. Some legacy plans require an upgrade to access 5G.
Verify 5G coverage at your location
Use Lyca Mobile's coverage map to confirm 5G is available at your exact location. Lyca Mobile 5G is available in major towns — rural areas may only have 4G.
Set preferred network type to 5G
Go to Settings → Mobile Service → Mobile Data Network → Preferred network type → select 5G/4G/3G/2G Auto. If this option is missing, your device or plan may not support 5G.
Remove SIM and reinsert
Power off. Remove and reinsert the SIM. Power on. This re-negotiates network capability with Lyca Mobile and can restore 5G after a registration glitch.
Disable 5G temporarily then re-enable
Set network type to 4G only, wait 30 seconds, then set back to 5G Auto. This forces a fresh 5G cell search on Lyca Mobile's network.
Contact Lyca Mobile if 5G never appears
If your device, plan and location all support 5G but it never shows, call 322 (free from Lyca). Lyca Mobile may need to update your SIM's 5G provisioning record.

Frequently Asked Questions

Why does my iPhone not show 5G on Lyca Mobile?

5G requires three things to align: a 5G-capable device, a Lyca Mobile plan that includes 5G, and 5G coverage at your location. If any one of these is missing, your iPhone will show 4G LTE instead. Check all three before concluding 5G is broken.

Is Lyca Mobile 5G free?

Lyca Mobile uses Vodafone UK 5G network. Check your specific plan in the Lyca Mobile app to confirm whether 5G is included. Some older Lyca Mobile plans predate 5G and may need upgrading.

What 5G speed can I expect on Lyca Mobile?

Typical Lyca Mobile 5G speeds range from 100 Mbps to 500+ Mbps depending on network load, distance from the 5G mast, and whether you are on Sub-6GHz or mmWave 5G. Lyca Mobile uses Vodafone UK 5G network.
