Solis Zero Is Not Connecting to a Mobile Network

If your device displays No Service, No Signal, or cannot connect to a mobile network, try the following:

1. Verify You're in a Covered Destination

Make sure you're currently located in a country or region included in your Solis Zero data plan.

2. Confirm Your Plan Has Activated

Your Solis Zero eSIM activates automatically the first time it connects to a supported mobile network in a covered destination.

3. Make Sure Your eSIM Is Enabled

Open your device's Cellular or Mobile Network settings and verify that your Solis Zero eSIM is turned on.

4. Select Solis Zero for Mobile Data

If your device has multiple SIMs installed, confirm that Solis Zero is selected as the active Mobile Data line.

5. Enable Mobile Data

Verify that Mobile Data is turned on.

6. Turn On Data Roaming

Many partner networks require Data Roaming to be enabled for the eSIM to connect successfully.

7. Confirm Your Phone Is Carrier Unlocked

Solis Zero requires a carrier-unlocked device.

If you're unsure, refer to the How to Check if Your Phone Is Carrier Unlocked article.

My Connection Is Slow

Mobile data performance can vary depending on your location and the local cellular network.

Common factors that affect connection speed include:

• Weak cellular coverage
• Network congestion during busy periods
• Distance from the nearest cellular tower
• Buildings, mountains, or other physical obstacles
• Local carrier network performance
• Device capabilities and software version
• Background applications using data

Tips to Improve Connection Speed

If your connection is slower than expected, try the following:

• Move to an area with stronger cellular coverage, such as outdoors or near a window.
• Wait a few minutes and try again if the local network is congested.
• Restart your phone.
• If your device supports it, switch between Automatic, 4G/LTE, or another available network mode.
• Close applications that may be using data in the background.
• Install the latest software updates available for your device.
