It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB

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.

Amazing service! I’ve used Mobimatter many times and I’m always impressed by how fast and helpful their support team is. They assisted me quickly whenever I had a question, and everything was resolved smoothly. The eSIMs are reliable, easy to install, and work exactly as expected. I keep coming back because the service is consistently excellent.

For our trip to China, South Korea, and Japan, my wife and I bought two 12GB data packages and used them without any problems. Their prices are much more reasonable compared to competitors; I definitely recommend them.

"Before every trip, my internet solution is definitely Mobimatter. It has never let me down. I once found myself without internet in the middle of a trip with another brand. Now, I don't take any chances; I stick to what I know."
