What You Get and What You Don’t
When you buy from Alt eSIM, you get an eSIM that roams on the Three network in destinations like Macau, Austria, and the UK. This means you can use data in these places with coverage from Three. However, it’s important to note that we are not Three and do not sell their official products. We offer our own eSIM that connects to their network. You won’t get any official Three branding or direct support from them. For example, if you’re traveling to Macau and need data, our eSIM will connect you to Three’s network there. But if you’re looking for Three’s own plans or products, you should look elsewhere.
Applicable Destinations
Our eSIM roams on the Three network in several destinations, including Macau, Austria, Denmark, Sweden, the United Kingdom, and Ireland. These destinations are covered by Three’s network, allowing you to use data seamlessly while traveling. For instance, if you’re visiting Austria and need to stay connected, our eSIM will utilize Three’s network there. It’s important to remember that this eSIM is only for these specific destinations. If you travel outside these areas, you won’t have access to Three’s network through our eSIM.
Choosing a Plan Shape: Daily vs. Total Data
When selecting a plan, you have two main options: daily plans and total data plans. Daily plans are great if you need flexibility and want to pay as you go. These plans offer daily allowances like 500MB, 1GB, 2GB, 3GB, or 5GB per day. For example, if you’re on a short trip to Sweden and need data for a few days, a daily plan might be the best choice. On the other hand, if you prefer a fixed amount of data for your entire trip, you can choose a total data plan with options ranging from 1GB to 50GB. This is ideal for longer trips to Denmark where you need a set amount of data.
Getting Connected
Connecting with our eSIM is straightforward. Once you purchase the eSIM, you’ll receive a QR code. You can scan this QR code with your device to activate the eSIM. After activation, your device will automatically connect to the Three network when you’re in a supported destination. For example, if you arrive in Ireland and your device is set up correctly, it will connect to Three’s network without any additional steps. It’s important to ensure your device is compatible with eSIM technology and that you have a stable internet connection to download the eSIM profile.
What Happens When the Allowance Runs Out
Once your data allowance is used up, your connection speed will drop to 128 or 384 kbps. This speed is still usable for basic tasks like browsing, checking emails, and using messaging apps. For example, if you’re in the UK and your daily 1GB allowance is used up, your speed will decrease, but you can still stay connected. However, for activities that require higher bandwidth, such as video streaming or large downloads, this speed may not be sufficient. It’s a good idea to monitor your data usage to avoid running out at an inconvenient time.
