Which eSIM works with dual SIM phones?
Real-world advice for autumn escapes and Black Friday bargains
It’s 5:55am on the day before Thanksgiving, and you’re standing in a hushed Heathrow terminal, phone in hand, staring at your mobile screen. Your physical SIM is still connected to your UK number, but you’re hunting for a way to grab local data the moment you land in New York—without fumbling for tiny plastic cards.
I’ve found myself in this exact scenario more times than I care to admit. Sometimes it’s a family trip to the US, other times a last-minute city break in Italy when the autumn air has that perfect chill. Each time, the question nags: will this eSIM actually work with my dual SIM phone, or am I about to miss an urgent work email?
Quick Facts
- Dual SIM phones let you use physical and digital SIMs at once—great for travel, if compatible
- Not all eSIMs, or phones, handle dual connections the same way—check before you fly
- Graba SIM eSIMs support instant activation, helping you avoid airport queues and shop counters
- Real-time data tracking with Data Pulse and widgets saves you from unexpected costs
- Switching between home and travel numbers is smoother with the right eSIM setup
City specifics: why dual SIM and eSIM matter on the ground
Spend a day in Manhattan during Thanksgiving week and you’ll see data speeds dip with every parade float that rolls past. I’ve watched my phone crawl when thousands of visitors log on at once. With an eSIM active on your dual SIM phone, you can grab a plan that piggybacks on the least congested US networks—sometimes AT&T, sometimes T-Mobile—without giving up your home number for banking codes or WhatsApp verifications. Or think about hopping between Greek islands. Physical SIM cards can be a logistical headache; kiosks don’t always stock the right size, and some islands close shop for the season. I’ve dodged this drama by activating an eSIM from Graba SIM the moment my ferry left Piraeus, then toggling between my UK line and the local Greek profile. Japanese autumn? Tricky, too. In Tokyo’s Shinjuku Station, the world’s busiest, most public Wi-Fi crawls to a halt during rush hour. Local eSIM plans can pair with your main SIM so you’re not cut off mid-navigation—especially handy for those labyrinthine exits (I’m still haunted by Exit E10).
Why This Matters
The right eSIM on a dual SIM phone lets you stay connected—with fewer headaches—right through seasonal travel surges, Black Friday chaos, or just your average autumn wander.
What dual SIM eSIMs actually deliver (from hard-won experience)
The big attraction, for most, is flexibility. On my iPhone 14 Pro, I routinely run my UK physical SIM for personal calls and a Graba SIM eSIM for data when abroad. No more juggling two handsets or missing out on 2FA codes from my bank. This setup is especially useful when your itinerary hops between countries—say, Amsterdam to Berlin to Prague. With regional eSIM plans, you can keep your UK number live while using local data across borders. One feature I wish I’d had years ago: Data Pulse. With Graba SIM, I get live data usage updates (down to the MB) and a home screen widget that acts like a speedometer for my travel budget—no more frantic toggling through settings or nasty “data exhausted” surprises. If anything goes wonky, their 24/7 live chat has always answered within minutes. No hyperbole—I’ve tested it at midnight in Seoul and at brunch in Lisbon. Instant activation is another quiet game-changer. Most eSIMs (Graba SIM included) can be scanned and live in under 30 seconds—faster than you’ll get a coffee at most European train stations. That’s made a huge difference when I land and need to hail a ride or check a booking.

Autumn city break in Paris
Used regional Europe eSIM for seamless data, kept home SIM for last-minute Airbnb verifications. Swapped data roles in seconds when crossing into Belgium.

Kept physical SIM dormant to avoid £50+ roaming bills, ran all data through a Japan-specific eSIM. Navigated Kyoto’s buses with Google Maps—no dropouts, even at dusk.
