TicWatch is Mobvoi's Wear OS smartwatch line. eSIM is available on TicWatch Pro 3 LTE and Pro 5 LTE — the standard non-LTE models have no cellular hardware. TicWatch Pro 5 runs Wear OS 3.5 and supports standard eSIM provisioning, meaning third-party data eSIMs like Roamix work without restriction.
Key Takeaways
- TicWatch Pro 3 LTE, Pro 5 LTE: eSIM supported.
- Standard TicWatch Pro 3 (non-LTE), E3, GTH: no eSIM, no cellular.
- Look for 'LTE' in the model name to confirm cellular hardware.
- Wear OS-based: standard third-party eSIM provisioning supported.
Does the TicWatch Support eSIM?
Only LTE models. TicWatch Pro 3 LTE and Pro 5 LTE include a cellular chip. Non-LTE TicWatch models — including the standard TicWatch Pro 3, TicWatch E3, and TicWatch GTH — have no cellular hardware. The model name always includes 'LTE' for the cellular variant.

Troubleshooting TicWatch eSIM
'Cellular' or 'Mobile network' option missing: You have the non-LTE TicWatch variant. Standard TicWatch Pro 3 (without 'LTE' in the name), TicWatch E3, and TicWatch GTH do not have cellular hardware. Check your model name — LTE support is always explicitly stated.
QR scan fails during activation: Your phone must have a stable Wi-Fi connection, and the watch must be in Bluetooth range during the scan. If the scan fails repeatedly, use "Enter activation code" in the Wear OS cellular setup for manual SM-DP+ entry.
Watch shows no cellular signal after eSIM setup: Open the Wear OS app or Mobvoi app → Device settings → Cellular → verify the Roamix profile is set as the active plan. If the profile is listed but marked inactive, select it and enable it.
"Cannot download eSIM profile" error: Retry on a more stable Wi-Fi connection — the download requires sustained connectivity. If the error recurs, the QR code may have already been used; contact Roamix support for a replacement activation code.
TicWatch Series eSIM — Frequently Asked Questions
Which TicWatch models have eSIM?
TicWatch Pro 3 LTE and TicWatch Pro 5 LTE have eSIM hardware. Standard TicWatch Pro 3 (non-LTE), TicWatch E3, TicWatch GTH, and other non-LTE TicWatch models do not have cellular capability. Look for 'LTE' in the model name to confirm.
How to tell if my TicWatch is the LTE model?
The LTE model name includes 'LTE' explicitly. You can also check the Wear OS app or Mobvoi app — if a 'Cellular' or 'Mobile network' option appears in the device settings, you have the LTE variant. Non-LTE TicWatch models will not show this option.
Can I use Roamix on TicWatch Pro 5 LTE?
Yes. TicWatch Pro 5 LTE runs Wear OS and supports standard eSIM provisioning. Activation: Wear OS app → Device settings → Cellular → Add mobile plan → Scan QR code. The watch must be in Bluetooth range of your phone during initial setup.
Does TicWatch eSIM work without a phone nearby?
Yes. After initial activation (which requires Bluetooth pairing with the Mobvoi or Wear OS app), TicWatch Pro 3 LTE and Pro 5 LTE connect to cellular networks independently — data, maps, and notifications work without your phone.
