Check Your Phone
To check if your phone supports 5G:
5G and Battery Life
5G can drain battery faster than 4G. Most phones let you disable 5G to save battery:
iPhone: Settings → Mobile Data → Voice & Data → 4G Android: Settings → Network → Mobile Network → Preferred network type → 4G/LTEIf you're in an area with weak 5G signal, your phone may constantly search for 5G, draining battery. Switching to 4G in these areas helps.
Networks Not Offering 5G
Some budget networks don't include 5G:
- Clear Mobile - 4G only (speed-capped at 5Mbps anyway)
- Tesco Mobile - 4G on most plans (5G on premium plans only)
- Lycamobile - 4G only
- Virgin Mobile - 4G only
If 5G matters to you, stick with 48 or GoMo for budget options.
5G Coverage: Future Outlook
All three networks are expanding 5G coverage. Expected developments:
2026-2027:- More rural coverage from Eir and Three
- Indoor coverage improvements
- Motorway coverage completion

Common Questions
Is 5G safe?
Yes. 5G uses radio frequencies that have been extensively studied. Regulatory bodies worldwide confirm 5G is safe at permitted power levels.
Will 5G replace home broadband?
For some users, yes. Three and Eir offer 5G home broadband. In areas with strong 5G, this can match or exceed fibre speeds. However, data caps may apply.
Does 5G work indoors?
5G coverage indoors is often weaker than 4G, especially in buildings with thick walls. This is improving as networks add more indoor coverage.
Can I turn off 5G?
Yes. All 5G phones let you disable 5G and use 4G only. Useful for saving battery or when 5G signal is weak.
