Mobile Wi-Fi, or MiFi, creates a wireless signal that compatible devices may share to access to the internet using your smartphone’s mobile data connection. It is especially helpful while traveling and out of range of a regular Wi-Fi connection or as a backup for shaky or overloaded home internet.
A portable device known as a mobile router or a mobile hotspot, into which you plug a SIM card, may also generate a mobile Wi-Fi connection. This procedure is known as internet tethering.
Mobile Wi-Fi routers might be the better option when used regularly since they won’t deplete the battery of your smartphone, you won’t have to mess about switching SIM cards, and you won’t have to leave your phone with whoever is using the shared internet connection. They may also be used with data-only SIMs, which are ones that do not support calls or messages but simply provide access to the internet.
A mobile Wi-Fi router and a mobile data dongle vary in that a router may share a mobile data connection with several devices while a dongle physically connects to your device. These days, only computers and older laptops that do not enable Wi-Fi access may genuinely benefit from USB dongles.
What benefits may you get from purchasing a portable Wi-Fi router?

You may link several devices together: It will be much less expensive to connect 10 or more MiFi devices to a single hotspot than to purchase a mobile data plan for each of those devices, but you’ll need a large data allotment.
Wi-Fi-only devices can be linked to a mobile data connection: Tablets are excellent for use at home, but what about on the train, at the beach, or at the swimming pool? You can use MiFi to set up a wireless network and access the internet from any Wi-Fi device anywhere you can get a phone connection.
On your next tablet, you may save money by: Before factoring in the monthly data charge, purchasing a tablet with a 4G or 5G data connection increases the cost by about £100. You won’t ever need to buy a cellular tablet again if you use some of that money to purchase a MiFi router.
The majority of cell providers offer free roaming in the EU (for the time being, at least! ), but fixed-price roaming abroad, enabling you to bring your home tariff with you for a predetermined sum. Turn off data roaming on all of your devices and connect them to a mobile hotspot to avoid paying this additional fee. You just need to pay this fee once to connect all of your gadgets to the internet. Although it is not yet widely available, 5G roaming is presently provided by Vodafone and VOXI.

Market interest was high when Duxbury Networking introduced Cudy’s budget-friendly routers in November. The WR2100 and WR1300 Cudy AC1200 dual-band Gigabit WiFi routers were the line’s first additions, but according to branch manager Paul Stuttard of Duxbury, the South African distributor of Cudy networking equipment, “the response has been so good that we are now rolling out further additions to the range.”

Because all Cudy desktop routers use TR-069 technology, service providers and Internet service providers may safely and remotely configure client premises equipment (CPE).
