Why New York eats data
- The subway has patchy signal — you'll lean on offline Maps but Citymapper, Apple Maps live updates, and music streaming push usage up between stations.
- Tipping apps, Uber, Lyft, Resy bookings are all data-hungry and you'll use them daily.
- Public Wi-Fi is widespread but slow. LinkNYC kiosks are fine for a quick check; for anything real, use your eSIM.
What allowance to pick
- Weekend trip: 5-7 GB.
- One-week holiday: 10-15 GB.
- Two weeks or business + leisure: 20-30 GB.
- Working from a NYC coffee shop: add an extra 5 GB for hotspot.
At JFK / Newark / LaGuardia
The eSIM connects to T-Mobile or AT&T 5G as you taxi to the gate. By the time you're at immigration, you can order an Uber, message your hotel and check the AirTrain timetable — no airport SIM kiosk, no $50 starter pack from a vending machine.
People also ask
- Will WhatsApp work on my UK number abroad?
Yes. WhatsApp is tied to your phone number, not to your SIM card or network. As long as your UK line is still active on the phone (even if data roaming is off), WhatsApp continues to send and receive messages on your UK number — using the travel eSIM's data connection. Voice and video calls work the same way.
- eSIM vs roaming — which is cheaper?
For almost every trip outside the EU, a travel eSIM is dramatically cheaper. A typical UK carrier charges £6 per day for roaming data outside Europe — that's £84 for a two-week trip with a 500 MB daily cap. The same trip on an A.R.I.A Mobile eSIM is around £10-£20 for 10-20 GB of data, with no daily caps and no bill shock.
- How much mobile data do I really need abroad?
For most travellers, plan on 1 GB per day. That covers Maps, WhatsApp, social scrolling, a few Ubers, and occasional video. Heavy users — daily video calls, streaming on the move, hotspotting a laptop — should plan 2-3 GB per day. Light users who mostly stick to Wi-Fi can manage on 500 MB per day.
- What is the best eSIM for business travel?
For business travellers, the best eSIM is a regional or global plan with at least 1-2 GB per day, 5G data, and instant activation. A.R.I.A Mobile business plans are billed centrally, support multiple devices per traveller (phone, laptop hotspot, tablet), and avoid the bill-shock that destroys roaming expense reports.
