TL;DR: Slow eSIM data is usually congestion, weak indoor signal, VPN, or the wrong partner network - not a broken install. Move, switch network, disable VPN, and retest.
Speed checklist
- Test outdoors or near a window.
- Disable VPN / Private DNS.
- Confirm 4G/LTE/5G (not EDGE).
- Try manual network selection among supported operators.
- Restart the phone.
- Check whether you hit a fair-use limit on unlimited-style plans.
Slow vs no data
If nothing loads, use connected but no data or no internet instead.
Plan choice tips
Heavy streaming needs more GB. Estimate with how much data do I need. Compare roaming costs in eSIM vs roaming.

Frequently Asked Questions
Why is travel eSIM slower than home 5G?
You use partner networks with local congestion, different bands, and fair-use policies on some unlimited plans.
Can manual network selection improve speed?
Yes. Switching from a congested operator to another supported network can help.
Does VPN slow eSIM data?
Often yes. Test with VPN off.
When should I buy more data?
If you hit a high-speed cap on an unlimited/fair-use plan, speeds drop until the next period or a new plan.
