You've purchased your eSIM, scanned the QR code, and arrived at your destination — but something isn't working. Don't panic. Most eSIM issues are caused by a handful of common configuration mistakes that are easy to fix. This guide walks through the most frequent problems and their solutions for both iPhone and Android devices.
Problem 1: eSIM installed but showing 'No Service' or 'No Signal.' This is the most common issue, and in the vast majority of cases it's caused by one setting: Data Roaming is turned off on your eSIM line. On iPhone, go to Settings > Cellular > tap your eSIM plan > enable Data Roaming. On Samsung, go to Settings > Connections > Mobile Networks > Data Roaming > enable it for your eSIM line. Despite the alarming name, enabling Data Roaming on your eSIM won't cause extra charges — you've already paid for your data through Hypr eSIM.
Problem 2: eSIM won't install or QR code scan fails. First, make sure you have an active internet connection (Wi-Fi or existing mobile data) — the eSIM profile needs to be downloaded during installation. If the QR code still won't scan, try these steps: ensure your camera is in focus and the QR code is displayed clearly (not on a cracked screen); try entering the activation details manually (Settings > Cellular > Add eSIM > Enter Details Manually on iPhone); and verify that your device is carrier-unlocked, as locked devices may block eSIM installation from third-party providers.
Problem 3: eSIM has signal bars but data isn't working. Check that your eSIM line is selected as the line for Cellular Data. On iPhone, go to Settings > Cellular > Cellular Data and select your eSIM plan. On Samsung, go to Settings > Connections > SIM Manager > Mobile Data and select the eSIM. If your phone is using your primary SIM for data instead, the eSIM will show signal but won't actually route any internet traffic.
Problem 4: eSIM suddenly stopped working mid-trip. This can happen if your data allowance has been exhausted, if the plan validity period has expired, or if your phone's network settings have been reset. Check your remaining data balance through the Hypr eSIM confirmation email or account page. If you've run out of data, you can purchase a new plan and install it alongside or in place of the expired one. If the plan is still active, try toggling Airplane Mode on for 30 seconds and then off — this forces your phone to re-register with the local network.
Problem 5: Phone shows 'eSIM is not supported' during setup. This means either your device model doesn't have eSIM hardware, or your phone is carrier-locked. To check eSIM compatibility on iPhone, go to Settings > General > About and look for a Digital SIM or eSIM section. On Android, go to Settings > Connections > SIM Manager — if there's no eSIM option, your device may not support it. Also confirm your phone isn't locked to a specific carrier, as this can prevent eSIM installation even on supported hardware.
If none of these solutions work, reach out to Hypr eSIM's customer support with your device model, the error message you're seeing, and a screenshot of your cellular settings. Most issues can be resolved remotely within minutes. The key takeaway: always install and test your eSIM before travelling. A two-minute test at home can save you a frustrating hour of troubleshooting at your destination.
