Roaming charges in the USA can ruin a great trip. You land, switch off airplane mode, and everything seems fine until your bill arrives. Traditional roaming often comes with per-day fees, data caps, and overage penalties. The smartest workaround is simple: use an eSIM with a local-rate data plan and keep your home number active for calls and texts.
Here’s a clear, practical guide to staying connected in the States without paying a premium.
Why roaming gets so expensive
When you roam, your home carrier pays a US network for access then passes the cost to you. That’s why daily travel passes look convenient but add up fast, and “included” roaming often comes with low data caps or speed limits.
With an eSIM, you skip the roaming middleman. You buy a USA data plan directly, at local-style pricing, and avoid the worst roaming charges in the USA altogether.
What an eSIM is (and why it helps)
An eSIM is a digital SIM profile built into modern phones. There’s nothing to insert or collect. You purchase online, receive a QR code, scan it, and your data works in minutes. Because it’s digital, you can run:
-
Your home SIM for calls/SMS/OTP codes, and
-
Your USA eSIM for fast, affordable data.
That combo gives you the best of both worlds reachability on your number and low-cost internet for maps, ride-hailing, tickets, and work.
Why choose Simonly Club for the USA
Simonly Club is a UK-based provider with easy, contract-free eSIM plans designed for short trips and longer stays. Plans are powered by O2 esim with trusted US partners for broad coverage, straightforward pricing, and quick activation by email. No stores, no plastic, no surprises.
Check your phone compatibility
Most recent iPhones (XS or newer), Google Pixels (3+), and Samsung Galaxy flagships (S20+) support eSIM. To check:
-
iPhone: Settings → Mobile Data/Cellular → Add eSIM
-
Android: Settings → Network & Internet → SIMs → Add eSIM
If you don’t see an “Add eSIM” option, your device may be incompatible or locked. Ask your carrier to unlock it before travel.
How much data you really need
Right-size your plan to your itinerary:
-
5–7 days (city trip): 3 - 5 GB if you use hotel Wi-Fi and avoid heavy video.
-
10–14 days (multi-city): 8–12 GB for maps, socials, a bit of streaming.
-
30–90 days (work + travel): 20–40 GB per 30 days if you do video calls and cloud docs.
Pick a plan you can top up online. Start modest; add data only if needed.
Activate before you fly (the calm way)
Airports are busy and Wi-Fi can be flaky. Install your eSIM at home on stable Wi-Fi:
-
Buy a USA eSIM plan from Simonly Club and enter your email.
-
Receive your QR code and instructions.
-
iPhone: Settings → Cellular → Add eSIM → scan QR.
Android: Settings → Network & Internet → SIMs → Add eSIM → scan QR.
-
Label lines “Home” (calls/SMS) and “USA Data” (eSIM).
-
Set Mobile Data to the USA eSIM line; keep your home line for calls/SMS.
-
After landing, toggle Data Roaming on for the eSIM line.
Now your apps use local-rate data while your number stays reachable.
Keep WhatsApp and iMessage on your number
Good news: WhatsApp and iMessage are tied to your identity, not to the data line. After installing the eSIM, your chats keep using the home number people already know, while data flows through your USA plan.
Hotspot/tethering on the road
Most Simonly Club plans allow hotspot, so you can share data with a laptop or tablet. Video calls can consume 1-1.5 GB per hour budget for that and use hotel Wi-Fi for big uploads. If you work on the go, consider a larger plan for headroom.
Data-saving settings that actually work
Little tweaks = big savings, especially if you’re worried about roaming charges in the USA creeping in through your home line by mistake.
-
Default Data Line: Confirm your USA eSIM is the active data line.
-
Turn Off Data Roaming on your home SIM to prevent accidental usage.
-
Offline Maps: Download areas in Google/Apple Maps before long drives.
-
Cloud Backups on Wi-Fi only: Set Photos/Drive/OneDrive to sync on Wi-Fi.
-
Disable Auto-Play Video in social apps.
-
Hotspot Low Data Mode: Limit background updates on tethered devices.
-
Email attachments: View online; download only what you need.
Coverage: cities, highways, and nature
You’ll find strong LTE/5G in big hubs like New York, LA, San Francisco, Chicago, Miami, Seattle, Boston, Austin, and DC. Highways and suburbs are typically solid; some mountain and desert regions can be patchy. Download offline maps for national park days and queue music/podcasts on Wi-Fi the night before.
Cost comparison (why eSIM wins)
-
Home-carrier roaming passes: Simple, but daily fees add up fast and often cap speeds/data.
-
Airport SIMs: Convenient, but usually overpriced with smaller bundles.
-
USA eSIM from Simonly Club: Clear plan sizes, local-style pricing, no contract, no physical hassle. You pay for what you need and top up only if you run short.
Avoiding roaming charges in the USA is mostly about not using your home line for data. The eSIM makes that easy.
Troubleshooting: quick fixes
If data doesn’t start after activation:
-
Toggle Airplane Mode on for 10 seconds, then off.
-
Set Mobile Data to the USA eSIM line.
-
Ensure Data Roaming is ON for the USA eSIM line.
-
Restart the phone.
-
If prompted, enter the APN from your setup email.
-
Still stuck? Ask support to resend the QR code.
Most issues resolve with the first two steps.
Can I extend to Canada or Mexico?
Trips evolve. Depending on the plan you choose, you may be able to top up or switch to a North America option. If you’ll cross borders, mention this when selecting your plan so you get the right coverage from day one.
Safety and privacy benefits
No kiosks, no passport photocopies, no SIM-tray fiddling in public. Your eSIM profile is tied to the device and can be disabled remotely if needed. Managing everything from your account keeps the process clean and secure.

An eSIM gives you local-rate data, instant activation, and freedom from daily roaming fees. Set it up before you fly, flip your data line after landing, and enjoy your trip with maps, messages, and meetings all working without the bill shock.
