Start with comparable units

Read price, currency, allowance and validity together. Ten gigabytes for thirty days does not mean ten gigabytes daily, and unlimited data does not guarantee constant speed. Prices below are public US-dollar listings observed on official pages; check the total before paying. This comparison examines five providers through published conditions, without claiming a SoftLuxNotes field test. First check device compatibility, carrier unlock and any US roaming already included in your contract.

Airalo: unlimited packages too

Airalo is not limited to fixed allowances. Its US offer includes unlimited packages for 7 days at US$25, 15 days at US$46 and 30 days at US$68. Choose using the product details, including whether it is data or data/calls/texts. For a short trip with modest usage, compare available fixed packages too: buying unlimited data does not automatically save money. Network names and allowances alone do not establish speeds along your route.

Holafly: check the hotspot allowance

Holafly US displays US$27.50 for 7 days, US$50.50 for 15 and US$73.90 for 30. Its prepaid product allows 1 GB of hotspot per day, an important constraint for laptop work or sharing. Unlimited data remains subject to local operators’ fair-use rules. Do not equate it with an unrestricted home connection or apply a global Holafly subscription’s conditions to this prepaid product.

Nomad: sale prices and activation window

Nomad lists 5 GB for 30 days at US$16 and 10 GB for 30 days at US$25. Its 20 GB, 30-day package appears at a sale price of US$36, not a guaranteed future rate. A seven-day unlimited package is also listed at US$23; read its specific conditions before comparing. The page requires activation within 60 days of purchase, otherwise activation occurs automatically. Some packages require a manual step described in the instruction email.

Ubigi: 10 GB, with an Alaska caveat

Ubigi’s US 10 GB, 30-day product displays US$14 and allows data sharing. Smartstart begins the plan on arrival in the covered destination; it expires if not activated within six months of purchase. Hawaii is included and Alaska excluded from this product. That detail can matter more than price: do not assume “USA” covers every stop without reading the list. The offer does not establish a field test or guaranteed minimum speed.

Keepgo: separate balance validity from price

Keepgo states that its eSIM data balance does not expire; prices and top-ups depend on the bundle. That may suit usage spread across several trips, but it does not confirm the old 25 GB for €90 offer or a standard 365-day validity. Check the actual bundle’s countries, networks and price before buying. With all five providers, keep instructions and maps offline: choosing the right package does not eliminate possible coverage gaps.
