Summary: Very easy to set up and works well. I initially tried it with an Orange SIM with a small data allowance and couldn't make it work. I don't know why but I am really not an expert. I then got a PAYG SIM from EE, bought a data add-on and it worked immediately. Absolutely no problems with it now I find it very useful.
Summary: This little device is so simple to use and being unlocked means it can be used anywhere in the world with a local SIM. Fantastic for holidays or for properties abroad where ADSL is expensive - totally mobile and easy to manage.
Summary: Grab yourself an unlimited/free data sim and this thing is brilliant! My phone is PAYG and I'm a nerd so it was just a matter of time before I got something like this. The E5331 works exactly as I'd hoped!
Summary: Just bought a Three Mobile Data Sim and off I went. No real set up to speak of. Was fairly plug and play. As a trainer I need to have back up wifi in case I go to a building that doesn't have it. This has saved me on a few occasions. No complaints. Am on my 2nd mobile 3G card (the ones I buy last 3 months each) - so have been using since Sept/Oct quite happily.
Summary: Very good, I was using it all the time but having borrowed it once, my husband has now stolen it !!! He is using it at work, on his meal breaks etc He is as impressed as I was. When we are out and about together we can use it to get on line with no problems.
Summary: After much reading I ordered a Huawei 5331. I used this with a Samba sim that gives me free internet. Easy to use and set up. Very pleased with this. Put on a window sill upstairs and whole house has wifi. The LEDs are basic red amber green but that keeps the price down. The Huawei app for android lets you see more detail and I have installed the widget on my phone. Overall works great. Only negative is no external antenna port but for this price I can live with that.
Summary: Our apartment in Spain does not have broadband nor access to wifi. The HUAWEI MIFI solution has been a great success. It allows me purchase sim time only when I need it and a reasonable cost. Strongly recommend it.
