When you travel abroad, you generally have three ways to stay connected: an eSIM, a rental Wi-Fi hotspot, or your home carrier's international roaming. This guide compares the cost and convenience of eSIMs versus rental Wi-Fi under conditions that are as similar as possible. The short version: if you're traveling solo and everything runs on your phone, an eSIM — where you buy only the data you need — tends to keep your connectivity costs lower. If you're sharing one device across a family or group, a rental Wi-Fi hotspot can be the more practical choice.
How rental Wi-Fi and eSIMs differ
| What to compare | Rental Wi-Fi | eSIM |
|---|---|---|
| Pricing model | Mostly charged per day | One-time purchase by data + days |
| Pickup / return | Pick up at the airport or by mail; return after your trip | Fully online; nothing to return |
| Carry / charging | You carry a router and keep it charged | Just your phone |
| Multiple people | Easy to share one device | Usually one device per plan |
| Best for | Families and groups; anyone unsure about setup | Solo trips, study abroad, business travel; anyone who wants to pack light |
Because rental Wi-Fi is billed per day, the longer your trip, the higher the total tends to climb. An eSIM is a one-time purchase tied to a data amount and a number of days, so it often works out cheaper for short to medium solo trips.
Example: 7 days in South Korea
| Option / plan | Approx. 7-day total (USD)* |
|---|---|
| Bloomy eSIM South Korea 1GB / 7 days | around $1 |
| Bloomy eSIM South Korea 3GB / 15 days | around $3 |
| Rental Wi-Fi, basic data, per day (×7) | roughly $20–25 |
| Rental Wi-Fi, 1GB/day, per day (×7) | roughly $40–45 |
*Rental Wi-Fi is compared at its per-day rate, eSIM at its data-by-days plan price. Figures are approximate USD estimates as of the research date (2026-06-15) and will vary with promotions, pickup method, insurance options, availability, and trip length. Confirm the exact price at the time of purchase.
Example: 7 days in Canada
| Option / plan | Approx. 7-day total (USD)* |
|---|---|
| Bloomy eSIM Canada 1GB / 7 days | around $2 |
| Bloomy eSIM Canada 3GB / 30 days | around $6 |
| Rental Wi-Fi, basic data, per day (×7) | roughly $55 |
| Rental Wi-Fi, 1GB/day, per day (×7) | roughly $60 |
| Rental Wi-Fi, North America regional, per day (×7) | roughly $70 |
*Same assumptions as above. North America regional coverage typically includes the U.S., Hawaii, Canada, and similar destinations. Confirm the exact price at the time of purchase.
Example: 7 days in France
| Option / plan | Approx. 7-day total (USD)* |
|---|---|
| Bloomy eSIM France 3GB / 30 days | around $3 |
| Bloomy eSIM Europe regional 3GB / 30 days | around $3 |
| Rental Wi-Fi, Europe regional, 1GB/day (×7) | roughly $50 |
| Rental Wi-Fi, 1GB/day, per day (×7) | roughly $60 |
| Rental Wi-Fi, basic data, per day (×7) | roughly $70 |
*Same assumptions as above. If your trip spans several countries, a regional (multi-country) plan is usually more convenient. Confirm the exact price at the time of purchase.
Example: 7 days in Thailand
| Option / plan | Approx. 7-day total (USD)* |
|---|---|
| Bloomy eSIM Thailand 1GB / 7 days | around $1 |
| Bloomy eSIM Thailand 3GB / 30 days | around $3 |
| Rental Wi-Fi, basic data, per day (×7) | roughly $18 |
| Rental Wi-Fi, 1GB/day, per day (×7) | roughly $50 |
*Same assumptions as above. Confirm the exact price at the time of purchase.
Which one is right for you?
For a short trip with light, solo use, a standard Bloomy eSIM data plan can cost less than renting a Wi-Fi hotspot. On the other hand, if you want to share one device with family or friends, or several people will be streaming video or working on laptops, a rental Wi-Fi plan with a larger or high-volume data allowance may suit you better. Don't compare on price alone — also weigh the practical factors: pickup and return, charging, and the risk (and cost) of losing the device.
Frequently asked questions
Which is cheaper — an eSIM or rental Wi-Fi?
For solo use, an eSIM — where you buy only the data you need — tends to keep your costs lower. If several people share one device, rental Wi-Fi can come out ahead. Prices vary with the conditions, so check current Bloomy eSIM pricing on our comparison page, and check rental Wi-Fi rates with each provider directly.
Can I use a phone number with an eSIM?
Bloomy eSIM is data-only. As a rule, it does not include a phone number for voice calls or SMS — there is no calling and no texting. For voice and messaging, use an internet-based app (VoIP / messaging apps such as WhatsApp) over your data connection.
In summary
Rental Wi-Fi is billed per day and shines when several people share one device; an eSIM shines for solo use, lighter packing, and skipping pickup and return. With Bloomy eSIM you can pick just the amount you need at a low price. Check the comparison page for details.
