Follow the Universal Link or Open Settings
  • Follow the Universal Link at the top of this email or:
  • Go to Settings → Cellular (or Mobile Data).
  • Under SIMs, tap your gsm2go eSIM (might have another name like Safe Travels, Business, or Secondary).
  • Tap Data Roaming.
Verify the QR Code

Set eSIM as Your Data Source
  • Make sure the eSIM is actually used for data: Settings → Cellular → Tap Cellular Data.

  • This prevents the phone from falling back to your primary line and accidentally roaming it.

iPhone Data Optimization (Recommended)
  • We recommend optimizing the use of cellular data while roaming — very effective, no downside.
  • Open "Settings" on your iPhone or iPad.
  • Tap on "Cellular" or "Mobile Data".
  • Scroll down and toggle "Low Data Mode" on.
  • Now switch off WiFi (for testing cellular data) and go to Airplane Mode for a few seconds.
  • Then turn off Airplane Mode and wait a few seconds for the phone to register on network and "climb up" the data protocols.
  • If data roaming is on, the indication on the top right corner will be 4G, LTE, or 5G.
If Data Still Doesn't Work
  • Make sure Mobile Data is ON globally.
  • Set APN to: mobiledata.
  • Toggle Airplane Mode ON → OFF.
  • Restart the phone.
  • Temporarily force LTE/4G only (some partner networks have roaming issues with 5G).
