Why is my travel eSIM not connecting?

Short answer. Most failures are a setting: the travel line isn't selected for mobile data, or data roaming is off for it. Check those two, toggle airplane mode, restart, and do not delete the eSIM, which is often single-use.

What should I check first?

  1. Line on, data on the travel line

    iPhone: Settings > Cellular > Cellular Data = travel line. Samsung: Settings > Connections > SIM manager.

  2. Data roaming on, for the travel line

    Holafly: "Make sure your data roaming is turned on when you reach your destination."

  3. Airplane mode on and off, then restart

    Apple lists restarting and checking for a carrier settings update (Settings > General > About) in its no-SIM steps.

  4. Check the plan has started and has data left

    Use the provider's app. Holafly's shows "Installed – In use" once a plan is active.

  5. Contact the provider before deleting anything

    Holafly: "don't delete the profile. Most are single-use and cannot be re-downloaded without contacting support." Apple: if your device has an eSIM, contact your carrier.

Could the phone be the problem?

If it is carrier-locked, it won't accept the profile: see how to check.
