Jolli TL;DR (The Short Version)
- ✅ Keep your UK number active for calls/texts while abroad.
- ✅ Use a Jolli eSIM for all mobile data to avoid roaming fees.
- ✅ No physical SIM swapping required; modern phones support both at once.
- ✅ Receive OTPs and banking texts without triggering daily charges.
We've all been there. You land in New York or Tokyo, ready to start your adventure. You want that sweet, fast data to find your hotel, but you also need to stay reachable. Maybe your bank wants to send you an OTP (One-Time Password) to let you buy that massive souvenir. Maybe your gaffer (boss) is texting to ask where that report is. Or maybe your mum just wants to make sure you didn't forget your coat.
In the old days, you'd have to swap physical SIM cards and hide your UK SIM in the back of your wallet, praying you didn't lose it in the airport lounge. Not anymore. Welcome to the era of Dual SIM magic.
Yes, you can use a Jolli eSIM and keep your UK number active.
Most modern phones (iPhone XS/XR and newer, and most recent Samsungs and Pixels) can handle two SIMs at the same time. This means you can keep your UK "Home" SIM active for calls and texts (so you don't miss anything important) while using a Jolli Travel eSIM for all your data.
The result? You avoid the £6-a-day "roaming pass" rip-off from your home carrier, but you're still reachable on your regular number. It's the ultimate traveller's hack.

How to Set Up Dual SIM on Android

Wait, will I still get charged by my UK provider?
As long as you only use your UK SIM for receiving texts (which is usually free) and you don't answer the phone or send texts back, you won't trigger those nasty daily roaming charges. For data, your phone will use the Jolli eSIM, which is prepaid and has zero roaming fees. No bill shock, just pure joy.
