eSIM Not Working? How to Fix the Most Common Problems

Signal but no internet

This is almost always a Data Roaming setting on the eSIM line specifically:

• iPhone: Settings → Cellular → tap the travel eSIM line → enable Data Roaming.
• Android: Settings → Network & internet (or Connections) → SIM manager → select the eSIM → enable Roaming or Data roaming.

Only enable roaming on the travel eSIM line — leave it off on your home SIM to avoid carrier charges. See Dual SIM travel tips for keeping lines separated correctly.

Slow speeds

• Confirm you bought the plan for the correct country or region — a mismatched plan can fall back to weak partner coverage.
• Toggle Airplane Mode or restart once to force a fresh network attach.
• Dense city centers, stadiums, and transit hubs get congested at peak times on any network, not just eSIM.
• Check that automatic cloud backup or app updates aren't running in the background and consuming bandwidth.

Still using home data instead of the eSIM

• iPhone: Settings → Cellular → turn off Allow Cellular Data Switching, which can silently flip data back to your home line.
• Android: check the preferred SIM for Mobile data in SIM manager — some phones default back to the physical SIM after a restart.

When to contact support

Email [email protected] with your order number if:

• The QR was never used before but still fails to install after multiple Wi‑Fi attempts
• Your plan is active in the dashboard but you consistently get no signal in a covered city
• You need a profile reissued after a device change

Never share your QR code publicly or send your account password — support will never ask for it.

FAQ

Why does my eSIM work in one city but not another?

Coverage runs on partner networks that vary by location. If a rural area or specific building has weak signal, that's a network limitation rather than a broken eSIM — download offline maps as backup.

I restarted my phone and now data is on my home SIM. Why?

Some phones reset preferred-data settings after a restart, or "smart" dual SIM features intervene. Manually reselect the travel eSIM for Cellular/Mobile data each time this happens.

Can I reinstall an eSIM that failed halfway through?

Usually yes, once on stable Wi‑Fi — most failed installs simply need a retry. If the profile shows as already used, contact support for a reissue.

Does deleting and reinstalling fix most issues?

Rarely necessary. Toggling Airplane Mode and checking Cellular Data / Data Roaming settings resolves the majority of cases without reinstalling anything.
