When you travel abroad, your main options for staying connected are an eSIM, a pocket Wi-Fi rental, or your carrier's international roaming. Here we compare the cost and convenience of eSIMs versus pocket Wi-Fi under conditions that are as close as possible. The short version: if you're traveling solo and everything runs on your phone, an eSIM — where you buy just the data you need — tends to keep your connectivity costs lower. On the other hand, if a family or group wants to share a single device, a pocket Wi-Fi rental can be the more convenient choice.
- For solo or short trips, an eSIM tends to be the cheaper way to stay connected
- Pocket Wi-Fi suits sharing one device, but the longer the trip, the more it adds up
- An eSIM is set up entirely online — nothing to pick up, nothing to return, no extra gear
- Bloomy eSIM offers low-priced plans across many countries (for example, a 1GB / 7-day Korea plan)
- It's data-only, so there's no phone number for voice calls or SMS — but app-based calls like WhatsApp work fine
How pocket Wi-Fi and eSIMs differ
| Comparison point | Pocket Wi-Fi rental | eSIM |
|---|---|---|
| Pricing model | Mostly charged per day | One-time purchase of data × days |
| Pickup / return | Pick up at the airport or by delivery, return after your trip | Fully online — nothing to return |
| Gear / charging | Carry the router and keep it charged | Just your phone |
| Multiple people | Easy to share one device | Generally one device per plan |
| Best for | Families and groups, or anyone unsure about setup | Solo travelers, students, business trips, anyone packing light |
Because pocket Wi-Fi is priced per day, the longer your trip runs, the more the total tends to climb. An eSIM is a one-time purchase for a set amount of data and days, which often works out cheaper for short to medium solo trips.
South Korea, 7 days: an illustrative cost comparison
| Option / plan | Rough cost for 7 days |
|---|---|
| Bloomy eSIM Korea 1GB / 7 days | Low-cost — often just a few US dollars (check the current USD price at checkout) |
| Bloomy eSIM Korea 3GB / 15 days | Low-cost — confirm the USD price at purchase |
| Typical pocket Wi-Fi rental (per-day) | Often several USD per day, so a week adds up to roughly tens of dollars |
Pocket Wi-Fi figures reflect typical per-day rental pricing; eSIM figures reflect a one-time data × days plan. Prices vary by provider, pickup method, coverage options, availability and trip length, so confirm the current price before you buy.
Canada, 7 days: an illustrative cost comparison

|---|---|
| Bloomy eSIM Canada 1GB / 7 days | Low-cost — confirm the USD price at purchase |
| Bloomy eSIM Canada 3GB / 30 days | Low-cost — confirm the USD price at purchase |
| Typical pocket Wi-Fi rental (per-day) | Daily rental rates in North America tend to be higher, so a week can run to a substantial total |
Same assumptions as above. Regional "North America" plans may cover the U.S., Hawaii, Canada and more; check the exact coverage with each provider.
France, 7 days: an illustrative cost comparison

| Typical pocket Wi-Fi rental (per-day) | A few USD per day, which still adds up across a full week |
Same assumptions as above. Confirm current pricing with each provider before booking.
Which one is right for you?
For a solo traveler with light usage on a short trip, a standard-capacity Bloomy eSIM plan can come out cheaper than renting pocket Wi-Fi. On the other hand, if you want to share one device with family or friends, or several people will be streaming video and doing laptop work, a pocket Wi-Fi rental with a high-data plan can be the better fit. Look beyond price alone and weigh the practical details too — pickup, return, charging and the risk of loss.
Frequently asked questions
Which is cheaper, an eSIM or a pocket Wi-Fi rental?
For solo use, an eSIM — where you buy just the data you need — tends to keep costs lower. When several people share a single device, pocket Wi-Fi can have the edge. Pricing depends on your specific plan and trip, so check Bloomy eSIM prices on our comparison page and rental Wi-Fi pricing on each provider's official site.
Can I get a phone number with an eSIM?
Bloomy eSIM is data-only, so it generally does not include a phone number for voice calls or SMS. You can still make calls through apps like WhatsApp over your data connection.
In summary
Pocket Wi-Fi is priced per day and shines when several people share one device, while an eSIM is the stronger pick for solo travel, packing light, and skipping pickup and return. With Bloomy eSIM you can choose a low-priced plan sized to exactly what you need. See the comparison page for details.
