These days, almost every iPhone is eSIM compatible. iPhone XS, XS Max, XR and all newer models support eSIM, including iPhone SE (2nd generation and later). Your iPhone also needs to be carrier-unlocked to use a travel eSIM.
Yes! iPhones without a SIM tray work perfectly with aloSIM. Your iPhone can hold many eSIMs at once, even though it can only use 1-2 at a time.
When you’re leaving for a new country, prepare your phone so it connects as soon as you arrive. On your iPhone, go to ‘Settings’ then ‘Cellular’ to make sure your eSIM is toggled on, with ‘Data Roaming’ toggled on. Then go back to ‘Cellular’ and select ‘Cellular Data,’ where you’ll select your aloSIM eSIM as your data source. You will connect to the internet as soon as you arrive (after toggling off Airplane Mode).
Absolutely, yes. iMessage and FaceTime will keep working normally with your Apple ID over any internet connection, including your aloSIM data. On your iPhone, go to ‘Settings’ then ‘Messages’ and ‘Send & Receive’ to make sure you can send/receive messages with your Apple ID.
This setting lets your iPhone use multiple SIMs for mobile data (internet) in case one has a weaker signal. It lives under ‘Settings’ then ‘Cellular’ and ‘Cellular Data’ on your iPhone.
Do not enable Cellular Data Switching, because you want your aloSIM eSIM to be your iPhone’s only data source when you’re travelling.
We recommend updating your roaming settings while you’re still at home. Toggle on ‘Data Roaming’ for your travel eSIM so it’s allowed to connect to all available networks. Toggle off ‘Data Roaming’ for your primary SIM so it cannot use the internet outside of your regular coverage area.
On your iPhone, go to ‘Settings’ then ‘Cellular’ and ‘Cellular Data.’ The selected SIM is the one your iPhone is using for all mobile data (internet).
Make sure ‘Allow Cellular Data Switching’ is toggled off, so your iPhone doesn’t try to use your regular SIM for internet abroad.
If you want prevent all roaming charges while you’re travelling, go to ‘Settings’ then ‘Cellular’ and fully toggle off your regular SIM — no calls, no texts, no internet, and no extra fees on your next phone bill.
