I used RedteaGO in mainland China and was truly impressed by the speed and reliability—much better than other local SIMs or eSIM providers. The app is clear and intuitive, activation was instant, and support responded quickly. Excellent value for money. I will definitely use it for my next trip.

I switched to RedteaGO as my primary travel eSIM and haven't looked back. If you're tired of paying tourist prices with the big names, this is the one to get. RedteaGO offers a really nice experience in China with good speed and very low latency. If you want hassle-free connection that won't blow your travel budget, try RedteaGO.

How it works

Make sure your device (iPhone, Samsung, Google Pixel, etc.) supports eSIM and is unlocked from your current carrier.

Install the RedteaGO app from the App Store (iOS) or Google Play (Android) on your eSIM-compatible smartphone.

Open the app, create an account with your email address (or log in via Apple/Google) and complete your user profile.

Browse the app to choose the travel country or region, then check available plans (data volume, duration, price).

Choose the plan that fits your needs (local, regional, or global), confirm your selection, and proceed with payment using accepted methods.

Upon arriving in the destination country, activate the eSIM in mobile settings and check that mobile data and roaming are enabled.

⚠️ If it fails

✅ Make sure your Wi-Fi connection is stable during installation, your device is eSIM compatible, and you have the latest version of the app. Try restarting the phone then retry the installation.

✅ Verify that the RedteaGO eSIM is selected as the mobile data line, toggle airplane mode on and off, then restart the device. Contact support via in-app chat if the issue persists.

✅ Check your usage via the RedteaGO app, disable automatic background updates, limit video quality, and close data-hungry apps.

✅ Contact RedteaGO customer service by email ([email protected]) or via in-app chat with proof of purchase. Refer to the refund policies of the chosen plan.
