Travel eSIM for Greece

An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone, tablet, or smartwatch that allows you to activate cellular plans electronically without inserting a physical SIM card. Unlike traditional SIM cards, eSIMs are reprogrammable, enabling you to switch carriers or plans instantly through software on compatible devices like iPhone 14, Samsung Galaxy S23, or Google Pixel 8.

To check if your phone supports eSIM, go to Settings → Cellular (iPhone) or Settings → Network & Internet (Android) and look for 'Add eSIM' or 'SIM card manager' options. Most flagship phones released after 2018 support eSIM, including iPhone XS and newer, Samsung Galaxy S20+, Google Pixel 3+, and many modern Android devices. You can also dial *#06# to see if an EID (eSIM identifier) appears.

To install your Hello Roam eSIM, follow these 3 steps: (1) Purchase your plan from the Hello Roam dashboard and receive your QR code via email within minutes, (2) Open Settings → Cellular → Add eSIM on your device (iPhone) or Settings → Network & Internet → Mobile Network (Android), (3) Scan the QR code or enter the manual activation code to complete installation in 2-5 minutes. Ensure you're connected to WiFi during setup.

eSIM activation is usually instantaneous but can take 2-10 minutes depending on carrier network conditions and signal strength. If activation takes longer than 10 minutes, try these troubleshooting steps: restart your device, toggle airplane mode on/off for 30 seconds, ensure the eSIM profile is set as your active data line, or check that you're in an area with adequate network coverage.

Yes, most modern smartphones support dual SIM functionality, allowing you to use one physical SIM card and one eSIM simultaneously. This is ideal for travelers who want to keep their home number active for calls and SMS while using a Hello Roam eSIM for affordable local data. You can choose which SIM handles calls, messages, and data in your device's cellular settings under 'Primary' or 'Default' line options.

5G support on Hello Roam eSIMs depends on the local carrier network included in your plan and your device's 5G compatibility. Many Hello Roam plans include 5G access where partner networks offer 5G coverage in major cities and urban areas. Your device must support 5G bands used in the destination country (check device specifications), and you'll automatically connect to the fastest available network (5G, 4G LTE, or 3G) based on coverage availability.
