We get this question VERY often!
"Which is better for me, sim card, or pocket wifi?"
There are plenty of points to take into account, but for the majority of people we talk to, it actually turns out to be more beneficial to rent a pocket wifi.
Generally speaking, there are a few major differences and a few advantages that Wifi routers have over sim cards:
1) Sim cards require your phone to be unlocked, and require some settings changes, while connecting to a WifiBuddy is as simple as connecting to any wifi network back home. I've heard a lot of horror stories from people thinking their phone was unlocked but it turned out to be incompatible with the network in Japan, etc.
2) Generally speaking, sim card's data plans are comparatively restrictive. There's nothing like our Platinum and PlatinumPlus plans (not even offered by other Wifi Router companies!), which, starting Feb 2, 2017 will offer 100GB of LTE-speed data per month, and beastly speeds.
3) When wanting to connect multiple devices, tethering to one phone can be bothersome. Not just because it's hard on the battery life of the broadcasting phone (requiring you to keep it connected to another battery, requiring more wires and mess!), but because all the connected devices are bottlenecked by that device's speeds. A WifiBuddy has it's own connection and broadcasting built-in, so everyone can experience solid speeds while sharing one.
4) We pride ourselves on having new devices with high speeds. This makes running multiple devices at satisfying speeds a lot easier than other methods. Older wifi models can't offer speeds as high, and many rental sim cards are running on networks borrowed from other networks, which are borrowed from other networks, so their speeds aren't prioritized.
We provide free 5-day shipping and free return shipping as well. We're able to provide overnight shipping to your hotel or local address as well if you need! We also include a free backup battery to extend battery life another 3-5 hours to 8-15 hours, depending on the device and how many devices are connected.
