To use it, do a Google search for the names of two phones, with a “vs” sandwiched between them. For example, Moto G5 Plus vs Moto E4 Plus.
Not all phones are included yet.
The SanDisk Connect Wireless Stick is new to me, and looks to be an excellent solution to the problem.
My particular phone will not accept a memory card, but it yours will be sure to get one…you can find 32 GB microSD cards for less than $12 in the Hot Deals section of FatWallet.com
The Hoo Too travel router, available in 3 different varieties on Amazon, has a nice feature: If you connect it to a wi-fi source intended for one device (say, the wi-fi on a plane or in a hotel room), you can then connect several devices to the Hoo Too.
This can save you substantial amounts of money during a trip. So far as the airline or hotel is concerned, you have only one computer connected to their wi-fi.
The least expensive Hoo Too travel router, the HT-TM02, has no battery and must receive power from a portable battery or other USB source. It costs only $18.99 with free Prime shipping. It weighs less than 2 ounces and is only about 2 inches x 2 inches. Think carefully before buying this one – do you really want a device that always has to be connected to an external power source to work?
For just $6 more you can get model HT-TM01 that has a battery with adequate life for most uses. That battery can also be used to re-charge your other devices, like a smartphone.
A third mode, the Titan, with pink top, has a larger battery for longer life and costs $40.
