| Group of 4 (7 days) | $19.96-$59.96 (4 eSIMs) | $56-$105 (1 device, split 4 ways = $14-$26 each) |

When eSIM Wins
An eSIM from HelloRoam is the better choice in these five situations.
Solo travel
You pay $4.99 to start with HelloRoam. A pocket WiFi rental for the same trip costs $56 or more. The math is simple for solo travelers.
Short trips
For trips under 10 days, an eSIM costs far less than a rental. No deposit, no return counter, no waiting.
Already have an eSIM phone
If your phone supports eSIM, you need nothing else. No extra device in your bag, no cable, no charging brick.
Multiple destinations
Visiting three countries? Buy a regional eSIM from HelloRoam. One plan covers multiple countries. Pocket WiFi often covers only one country per rental.
Value convenience
Activate your eSIM before you leave home. Data is live the moment you land. No pickup counter, no queue.
When Pocket WiFi Wins
Pocket WiFi makes sense in three specific situations.
Group of 3 or more
One pocket WiFi device shared between four people costs $14 to $26 each for a 7-day rental. Individual eSIMs for four people cost more in total.
Phone does not support eSIM
Many budget and mid-range Android phones lack an eSIM chip. If your phone only has a physical SIM slot, pocket WiFi gives you a data option without swapping SIMs.
Need to share with a laptop
Pocket WiFi acts as a WiFi hotspot. Your laptop, tablet, and phone can all connect at once. eSIM tethering from your phone works too, but drains your phone battery faster.
Pocket WiFi in Japan: Is It Still Worth It?
Japan built a strong pocket WiFi rental culture. Providers like Sakura Mobile and Ninja WiFi let you pick up a device at the airport and drop it in a return box before your flight. For years, this was the easiest way to get data in Japan.
That changed when Japanese carriers opened their networks to eSIM. HelloRoam (8.8/10, 31/31 activations) now offers Japan eSIM plans starting at $4.99. You activate before departure, skip the rental counter, and avoid the return box entirely.
For solo travelers and couples visiting Japan, eSIM now costs less and takes less time. Pocket WiFi in Japan still makes sense only if you travel with three or more people who plan to share one device.

Speed and Reliability
eSIM connects your phone directly to a local carrier tower over 4G or 5G. There is no intermediate device between you and the network. You get the same speeds as a local SIM card.
Pocket WiFi works differently. The rental device connects to a cell tower, then broadcasts a WiFi signal your phone joins. This wireless hop between the pocket WiFi device and your phone adds latency. In areas with strong signal, the difference is small. In crowded places like airports or train stations, the extra hop makes a noticeable difference.
Pocket WiFi also fails if the device battery dies or gets left behind. With eSIM from HelloRoam, your data stays on your phone. There is no second device to lose or forget.
eSIM speed path
Phone connects directly to carrier tower over 4G or 5G. Single hop. Full carrier speeds. HelloRoam uses 204+ carrier networks for best available signal.
Pocket WiFi speed path
Pocket device connects to carrier tower, then broadcasts WiFi to your phone. Two hops. Adds latency. Signal quality depends on both the carrier and the WiFi broadcast range.
