Common causes
Network congestion
In busy areas (tourist hotspots, events, rush hour), the local network can be congested. Speeds typically improve during off-peak hours.Limited coverage area
Rural or remote areas may only have 3G coverage, which is naturally slower than 4G/5G.Network selection
Your phone may have connected to a slower network. Try manually selecting a different network:- iPhone: Settings > Mobile Data > tap Roamly eSIM > Network Selection > turn off Automatic and select a different carrier.
- Android: Settings > Network & Internet > SIMs > Roamly eSIM > Network operators > select manually.
Things to try
- Toggle the eSIM off and on to force a fresh network connection.
- Restart your phone.
- Move to a different location — even a few hundred metres can make a difference in signal quality.
- Switch network manually — Try connecting to a different carrier from the available networks list.
- Check your data usage — If you’ve used all your high-speed data, some plans may reduce speeds. Check your usage on My eSIMs.
Expected speeds
- 5G: Up to 100+ Mbps
- 4G/LTE: 10-50 Mbps
- 3G: 1-5 Mbps
