Who we are. Keyanok is an independent information and guidance service for United Kingdom mobile customers. We are not a mobile network. We have no affiliation with, endorsement from, appointment by or connection to Three, EE, O2, Vodafone, Sky Mobile, Tesco Mobile or any other provider, and no commercial arrangement with any of them. We do not sell, supply, arrange or broker SIM cards, contracts, handsets or services of any kind, and we take no commission. Everything on this site is general information; a provider’s own current terms always take precedence.
The facts
- Older phone dropping calls
- 3G has been switched off
- One bad room
- Building materials
- Full bars, no data
- Congestion
- Whole street out
- Mast work or a local fault
What it means for you
| What you see | Usually | What fixes it |
|---|---|---|
| An older phone dropping calls | 3G has been switched off nationally | Turn on 4G Calling; if the phone cannot, it is finished |
| One room always bad | Building materials blocking radio | Turn on Wi-Fi Calling |
| Full bars, nothing loads | Too many phones on one mast | Nothing on the handset helps |
| Whole street out for hours | Mast work or a local fault | Check the status page by postcode |
| Slow only at home | Your router or Wi-Fi, not the network | Test with Wi-Fi switched off |

- 4G Calling, if the phone supports it
What it means for you
Third-generation service has now gone across the country. A phone that has suddenly started failing on calls is very often reaching for something that no longer exists.
Turning on 4G Calling is usually the whole cure. Where a handset cannot support it, that device has reached the end of its useful life on any UK network — no amount of complaining will bring 3G back.
The facts
- Log for
- A fortnight
- Record
- Dates, times, what failed
- Then
- Complain in writing with the log
- Ask about
- Goodwill for the recorded period
What it means for you
One bad day is bad luck. A pattern is evidence — but only if you write it down.
- Log dates, times and exactly what failed for two weeks.
- Complain in writing with the log attached.
- Ask directly what goodwill applies to the recorded period.
- If it is refused or ignored, escalate free to the Communications Ombudsman at eight weeks.
Watch thisCredits for sustained or repeated loss of service do get agreed — but they get agreed on dated written evidence, not on how annoyed you sound on the phone.
