Slow eSIM internet? Why it happens and how to fix it

Slow eSIM internet is usually caused by a busy or weak local network, a setting such as a VPN or Low Data Mode, or, on FLEX365, having used the day's high-speed allowance. Reconnecting and trying another partner network fixes most cases.

On FLEX365? Check your daily allowance first

FLEX365 includes a high-speed allowance for each 24-hour cycle. After you use it, the connection continues at reduced speed under the Fair Usage Policy until the next cycle. Cycles reset 24 hours after the time your plan activated, not at midnight. Hotspot use counts toward the allowance.

Why your eSIM uses LTE or 4G instead of 5G

For 5G you need a 5G phone, a plan and partner network that offer 5G, and 5G coverage where you are. Many travel plans use LTE/4G. Seeing "LTE" or "4G" is normal and does not mean the eSIM is faulty.

Quick fixes for slow eSIM internet

1. Turn Airplane Mode on for about 30 seconds, then off.
2. Restart the phone.
3. Move to a spot with better coverage. Thick walls, basements and trains can weaken the signal.
4. Try another partner network: see how to select a network manually.
5. If the 5G signal is weak, switch to LTE. iPhone: Settings > Cellular, tap the travel eSIM, then Cellular Data Options > Voice & Data > LTE. Samsung: Settings > Connections > Mobile networks > Network mode. Pixel: Settings > Network & internet > SIMs, tap the eSIM > Preferred network type.
6. Turn off any VPN, and turn off Low Data Mode (iPhone) or Data Saver (Android) while you test: see settings that slow or block eSIM data.
7. On Pixel, Battery Saver turns off 5G. Turn it off if you want 5G.
8. Install any software update.

Test the speed fairly

Speeds change with location and time of day. Networks are busiest in city centres, at events and in the evening. Test again in a different place or at a quieter time before deciding the eSIM is slow.

Quick answers

Why does my phone show LTE or 4G instead of 5G?

5G needs a 5G phone, a plan and partner network that offer 5G, and 5G coverage where you are. Many travel plans use LTE/4G, so seeing LTE or 4G does not mean something is wrong.

When does FLEX365 high speed come back?

The daily high-speed allowance resets every 24 hours from the time your plan activated, not at midnight.
