Product description

Product Details 1. Applicable Region: Japan, covers the whole of Japan 2. Duration of Use: 15 days (the day of successful activation is counted as the 1st day) Activation Method 1. Upon arrival at your destination, insert the data card (If you are using a dual-SIM smartphone, please put it into the SIM 1 card slot.) 2. Enable data roaming in your phone settings and keep network selection on automatic. Wait for your phone to automatically search for and connect to the network provider. 3. Automatic network search may take about 5-10 minutes (depending on local signal reception). 4. After successfully searching for and connecting to the network provider, activation is complete. 5. A user manual is packed with the SIM card. Important Notes Ensure that the signal reception at your location is good. Network speed may vary depending on location, surrounding environment, usage period and device. Any connection failure due to bad weather or rural areas is the responsibility of the local service provider. If you still can't access the internet properly, please restart your phone. Frequently Asked Questions (FAQ) 1. Why is my SIM card not working immediately after insertion? Make sure to follow the activation instructions provided with the SIM card. The activation process may take some time, so please be patient. A stable connection is required for the SIM to activate fully. 2. Why do I lose connection after a few days? This happens when you have used up all the high-speed data included in your plan. Once the data limit is reached, your connection will switch to a slower speed, but the SIM will still remain active. 3. How can I avoid slow speeds during my trip? To ensure continuous high-speed connectivity, choose a data plan that matches the duration and usage needs of your journey. Be mindful of your data consumption to avoid running out too soon. 4. What should I do if the SIM still doesn’t connect? Double-check the activation steps and ensure your device is compatible with the SIM. If issues persist, reach out to customer support for assistance.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
