Does a Guernsey eSIM come with a phone number?
Most travel eSIMs, including most Guernsey plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Guernsey eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.
Can I keep my own SIM and WhatsApp while using a Guernsey eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.

"I think this is the fourth time I'm using it abroad. There was only one issue, but the support was very quick. It feels like they are waiting at the screen for fast help. The problem was identified in seconds and a new QR code was sent. Thank you very much."

I have been using MobiMatter for a few years both for travel and to supplement my regular cell plan which has limited data. The service has always been solid and the prices excellent. The installation instructions are easy to follow. On the few occasions that I asked for tech support (mostly for my own errors) the response time has been amazing and the support courteous and effective.

Since I started using MobiMatter, I have never once encountered a problem that they haven’t responded to almost immediately. I guess this is what sets them apart. Excellent customer service, very detailed troubleshooting instructions, and a support team that genuinely follows through until the issue is resolved. The app is easy to use, the eSIM installation process is straightforward, and the profes are competitive. Highly recommended for anyone who wants reliable connectivity while travelling.
