Stop overpaying for roaming

You shouldn’t have to worry about high roaming costs while traveling. BT may charge expensive roaming fees, leaving you with unexpected bills—but that’s not how it should be.

There’s a smarter way: Firsty! Compare BT's international roaming costs with Firsty’s simple, affordable data plans. Transparent mobile data costs, Firsty ensures no surprise charges—just reliable global coverage at a fraction of the cost.

Using Firsty while traveling internationally can save you up to 90% on roaming fees—without compromising on coverage. BT limits you to a single partner network in each country, Firsty connects to multiple networks, always selecting the best available one for faster, more reliable data.

Aww, we love you too!!

Excellent application
I was comparing Firsty plans to Orange roaming plans before my trip to Egypt and I found out that Firsty gives an unlimited internet for the same price as Orange does. Plus the UI of the app is much user-friendly. Look no further

It just works!
Was not sure what to expect but worked flawlessly when traveling. They have me hooked for every time I travel.

So simple!
So quick, easy & reasonable - just set up before you leave and you’re sorted for when you land! First time using an eSIM and it’s a lifesaver!

Best app while roaming 5 Edit Response
We tried this whilst travelling in Spain, and for minimal amount of money per day, you have unlimited internet. It’s easy and super helpful. Goodbye physical sims, waiting at airports.. we love it and recommend it

Fantastico! Viaggio molto per lavoro, uso spesso eSIM ma Firsty è sempre con me come backup e non delude mai, persino il piano free con ad mi permette messaggi call a maps quando serve fuori ue

I have used this app multiple times in the USA and have recommended it to others as well. I am so happy and impressed with it. I can’t recommend it enough to others.
