Maryland eSIM Travel Guide
Buy a Maryland eSIM for Chesapeake and beach travel
Combining Baltimore, Annapolis and Ocean City in one Maryland trip? Choose AloOui's existing United States eSIM for maps, reservations and messages where supported local mobile coverage exists. Your QR code is emailed after purchase. This is a Maryland trip guide, not a separate state-only product or a Washington, DC page.
Compare total and daily allowances and choose validity for the city, bay and beach days. Prices can change; check the live total and plan terms before checkout.

Fixed data
One total allowance for selected validity, not a daily reset.
Unlimited Lite
Shown as United States of America Unlimited. Compare daily full-speed and reduced-speed terms.
Unlimited Essential
A balanced daily tier for maps, reservations and messages. Check exact full-speed terms.
Unlimited Plus
For heavier use, compare daily allowance, validity and hotspot terms. Plus is not Premium.
No Premium tier is selectable on the US product. Check data, speed, hotspot conditions and current price on the United States plan page. More data cannot create offshore signal.
Baltimore arrival
Save the airport on your ticket, accommodation address and transfer booking before leaving Wi-Fi. Keep venue confirmations offline. Supported data can help with maps and messages, but reception can vary inside large buildings and busy venues. The eSIM does not include attraction entry or transport.
Annapolis and Chesapeake Bay
Choose validity for the bay portion of your itinerary and save operator meeting points and return details. Check weather, sailing schedules and safety guidance with your provider. Do not assume reception aboard a boat or offshore, and never rely on mobile data as your only safety tool.
Ocean City beach days
Keep lodging, parking or transport details and return plans offline. Check beach access and local weather notices before setting out. Service can vary along the coast or indoors; the eSIM is for supported mobile coverage, not a guarantee of signal on every beach or pier.
Need a US phone number too?
The data eSIM and the United States Virtual Phone Number are separate products. The virtual number is a monthly subscription that renews automatically. Check calling and messaging terms; do not assume a number, calls or SMS come with the data eSIM.
Install and troubleshoot
- Choose a United States plan and validity, complete checkout and open the emailed QR code on another screen.
- Connect an unlocked eSIM-compatible phone to Wi-Fi. Add an eSIM from iPhone Cellular/Mobile Data settings or Android SIM manager/Network settings, then scan the code.
- Label the line AloOui and follow the delivery email. Do not delete the installed eSIM.
- On arrival, select AloOui for mobile data and follow the plan's activation instructions. If data fails, check validity and instructed roaming, toggle airplane mode and check any APN instructions. Visit the AloOui Help Center for assistance.
