How to Connect LTE Samsung Watch: A Step-by-Step Guide

Samsung’s line of smartwatches are some of the most advanced on the market, offering a range of connectivity options to keep you linked 24/7. While all Samsung watches can connect to your smartphone via Bluetooth, LTE models provide cellular connectivity allowing you to use data services, stream music, and more even when your phone isn’t nearby.

However, setting up that seamless LTE connection can confuse some users. In this comprehensive guide, we’ll walk you through the step-by-step process of getting your LTE Samsung watch hooked up and connected. You’ll also learn key information on using LTE services, managing your cellular plan, and troubleshooting issues. So strap on your Samsung Gear and let’s get started!

Choosing an LTE Samsung Watch Model

Samsung offers LTE connectivity on select models in both their Galaxy Watch and Gear lines. Current LTE-enabled options include:

  • Samsung Galaxy Watch 5
  • Samsung Galaxy Watch 5 Pro
  • Samsung Galaxy Watch 4
  • Samsung Galaxy Watch 4 Classic
  • Samsung Galaxy Watch 3
  • Samsung Gear S3

When shopping for these models, be aware that LTE support comes standard on some versions but requires upgrading in others. Also, not all carriers or countries offer LTE service on Samsung watches so check compatibility.

Understanding Your LTE Service Options

Activating LTE functions on your Samsung watch requires adding it to your existing phone plan or signing up for a standalone service. Here are the differences in how it works:

Phone Plan LTE Service

  • Most convenient option
  • Share data allowance from the smartphone plan
  • Average $10 extra monthly device fee
  • Number shares same phone number

Standalone LTE Plan

  • Watch has its own data/voice plan
  • Average $5 to $10 monthly
  • Gets assigned a unique number
  • Must pay an activation fee

Consider data usage needs, costs, and your convenience preference when selecting the right connectivity option. Your cellular carrier should clearly disclose all fees so you know what to expect.

Activating LTE on Your Samsung Watch

The activation process will vary slightly depending on your mobile carrier but involves these general steps:

  1. Insert activated Nano-SIM card into watch
  2. Turn on standalone power on watch
  3. Complete activation through carrier app or website
  4. Wait for service to fully activate

Critical points for smooth activation:

  • Use correct size Nano-SIM card
  • Ensure watch battery charge over 50%
  • Download carrier apps if instructed
  • Restart devices as needed

It may take 15-60 minutes for activation to fully complete. If you run into issues, contact customer support.

Connecting Standalone LTE Watch Plans

If adding your Samsung watch via a standalone plan, you’ll first choose a cellular carrier that offers watch connectivity. Most major providers like Verizon, AT&T, and T-Mobile support LTE wearables.

Once signed up, you’ll receive the Nano-SIM card required to enable data services. Simply insert into your Samsung watch following the instructions included from your carrier.

The last step involves completing activation via the website or app provided. Usually you must verify the SIM’s number for security purposes. If all goes smoothly, you’ll see LTE coverage icons like on a smartphone appear indicating you’re ready to use cellular data.

Adding to Existing Phone Plan Rather than a separate bill, many opt to add wearable devices onto existing unlimited plans. The Samsung LTE watch appears as an additional connected device for usually around $10 per month.

First, work with your carrier to get set up officially. In some cases, this includes assigning the paired mobile number to the watch rather than its own. Verizon NumberShare and AT&T NumberSync enable this functionality.

After any required SIM card activation, open the Galaxy Wearable app on your synchronized Android device to finish. Under “Mobile networks” enable cellular data for instant access everywhere untethered from your smartphone.

Using LTE & Managing Your Cellular Data

Once connected, the LTE icon at the top of your Samsung watch face confirms mobile data is live. To control usage:

  • Set only essential apps to use LTE in Watch Settings
  • Enable LTE usage alerts and data tracking
  • Toggle cellular data manually when unneeded
  • Switch LTE off completely for battery conservation

Use WiFi instead of LTE whenever available to prevent excessive charges. Customize how apps rely on cellular data for maximum efficiency.

Regularly monitoring activity in the Galaxy Wearable app lets you catch any spikes indicating potential problems. Disable LTE temporarily if something seems amiss.

Troubleshooting LTE Connection Issues

Can’t get LTE working on your Samsung watch? Following this troubleshooting checklist should help narrow down the problem:

  • Verify LTE plan is active with your carrier
  • Try removing and reinserting SIM card
  • Check for watch software/firmware updates
  • Toggle cellular data off/on
  • Factory reset watch to refresh settings
  • Contact carrier/Samsung support for assistance

If LTE functions initially but then stops working, reconnect by restarting your watch and paired phone. This often resolves connection issues.


Equipping your Samsung Galaxy Watch with LTE connectivity unlocks exciting capabilities for staying in touch on the go. But realizing that functionality requires careful activation plus understanding options for service plans and data management.

By following this guide, your wearable device can now grant you calls, messages, streaming, and more minus the need for lugging a smartphone. Just take the time upfront to get LTE properly set up. Then enjoy that feeling of freedom as your wrist buzzes with notifications no matter where life takes you.
