Buyers Guide: Avoid Common Mistakes

  • !Don't buy a US model for use in Europe (LTE bands differ).
  • !Check if your carrier allows smartwatch eSIM on prepaid plans (often post-paid only).
  • !Don't expect Garmin LTE to replace your phone for voice calls.
  • !Remember the monthly carrier fee (usually $5-$10/mo).
  • !International roaming rarely works on wearables.
  • !You can't upgrade a GPS-only watch to LTE later (hardware is missing).
  • !LTE drains battery 3-4x faster than Bluetooth.
  • !Family Setup (Apple) requires a specific carrier plan.

Frequently Asked Questions

Do Garmin watches have eSIM?

Most Garmin watches do NOT have standard eSIM for calls and texts. Some models, like the Forerunner 945 LTE, have LTE safety features (Assistance Plus, LiveTrack) requiring a subscription, but they cannot make standard phone calls or send SMS like an Apple Watch.

Can I use one eSIM for both phone and watch?

Typically, you use NumberShare (or Digits/NumberSync) which links your watch's eSIM to your phone number. You don't physically swap one eSIM; the carrier provisions a secondary eSIM profile for the watch that shares your main number.

Do LTE watches work without my phone nearby?

Yes. If activated with a carrier plan, LTE watches can make calls, stream music, and use maps without your phone. However, battery life is significantly reduced when using LTE exclusively.

Do I need an extra plan?

Yes, carriers usually charge a monthly fee (often $5-$10) for a smartwatch data plan to enable LTE features.
