An eSIM (embedded SIM) is a built-in SIM card in your smartphone that replaces your physical SIM card and is digitally activated.
Most newer smartphones and tablets are eSIM compatible. You can find all eSIM-enabled devices over here. The following requirements must also be met: Roaming must be activated on your device and there must be no SIM lock.
No, with BuddySIM, there are no roaming charges for your main contract.
The validity period and data consumption of your eSIM package only start when data roaming is activated on your device and the eSIM connects to the network. The date of the first data consumption is therefore the start of the validity period of 7 or 30 days. If you are planning a trip in the future, you can easily install your BuddySIM beforehand and only activate data roaming when you start your trip.
No, you have no contractual relationship with your BuddySIM. It is a pure prepaid eSIM whose term ends after 7 or 30 days or as soon as your data volume is used up. So you don't have to cancel anything!
The eSIM only allows you to use mobile data. It does not include a local number for receiving or making calls or messages.
Sure, with your BuddySIM eSIM, you can continue using WhatsApp with complete peace of mind. Your WhatsApp number remains the same even if you activate our eSIM. This means that all your chats and contacts are still there and you can make calls via WhatsApp.
Of course, with your BuddySIM eSIM, you can assign a hotspot for your laptop or other devices as usual. Your speed is never throttled and consumption is also not limited. You can therefore use the entire volume of booked data via the hotspot. 👍🏽
If you have already bought a BuddySIM and your data volume has been used up, you can easily do it via whatsapp recharge without installing a new eSIM. Just send us a message with the keyword “Top Up”.
Common causes: eSIM not installed or activated, mobile data and data roaming are disabled, compatibility issue with your smartphone, no network coverage at the location. Tip: Check your settings and always install the eSIM on Wi-Fi. If you have any problems, our support team will help you.
Basically, 4G & 5G coverage in urban areas in the USA is very good. We have had excellent experience with AT&T and T-Mobile USA and use precisely these networks for optimal performance in both rural and urban areas. If you are undecided, contact us at any time and we will find the best network for your trip to the USA.
The best eSIM USA depends on how long you stay and how much data volume you need. With BuddySIM, you get flexible packages of 5, 10 or 20 GB and terms of up to 30 days — ideal for trips, road trips or work. Our USA package uses a strong local network (such as AT&T or T-Mobile) for optimal speed and coverage.
The BuddySIM USA digital eSIM from BuddySIM is ideal for tourists: No waiting for mail delivery, immediate installation, various data packages to choose from and full flexibility. Perfect for your vacation, with no roaming costs.
The activation process must be divided into two steps: installing the eSIM and activating the eSIM. Installing is scanning the code or manually entering the eSIM on the smartphone. Ideally, you can “install” your BuddySIM one day before departure. The eSIM is then on your device but is not yet active. Mobile data can only be activated in the destination country. You “activate” the eSIM by turning on data roaming for the eSIM and selecting it as a line for mobile data. ► Ideally install your BuddySIM one day before departure — and activate it in the destination country: the data only starts in the destination country, so you don't lose any runtime or data volume.
We recommend that you only activate your eSIM USA when you arrive in the USA. The runtime starts with the first use, so you can install in advance, but you should only activate mobile data and data roaming in the destination country.
Your BuddySIM works with all eSIM-enabled smartphones. The full list of compatible smartphones can be found at buddysim.com/check.
For 2 weeks in the USA, we recommend 5-10 GB, depending on how intensively you use the mobile network. For Google Maps, WhatsApp, emails, and occasional streaming, 5GB is often enough. Anyone who uses social media or videos on a daily basis should use 10 GB. With BuddySIM, you can reload flexibly.
After purchasing your BuddySIM, you will receive your QR code and manual activation data directly via email to the email address you provided.
