Just installed, may change review later, but so far it works smoothly on my HP laptop using a T-mobile SIM and has a very small memory & storage footprint. Can't ask for much better!
Installed and activated without any difficulty, and thus enabled an advance against another problem. I'm using a desktop computer that occasionally is connected to the internet via a USB device that offers "Mobile Broadband" via the cellphone system at up to 2M bits/sec occasionally but more often around 100K b/s if I'm lucky and slower still with pauses too. So not very broadband. However, it is much cheaper than a fixed fibre-optic connection, and I watch movies on the big silver screen, thanks. The device was supplied by Vodafone some years back, and the account could be managed via its webpage. Then the webpages were redesigned. Recently, Vodafone New Zealand became "One" and there was a new design. The account could be managed via an "app" on the cellphone, except, this is not a cellphone, damnit! A website is offered as a fallback, but to use it, a security code is sent via a txt message to the cellphone, and THIS IS NOT A CELLPHONE, DAMNIT!! so I couldn't see the five-digit number and so couldn't enter it and so couldn't access the account details via the website. (This is a dual-boot system, and on the windows side, I could receive the SMS message thanks to the original Vodafone software, but, the web page wouldn't work!) But now, enter chatty! The SMS ws received, the number was shown, I entered the number to the webpage, and behold, the account was shown by the webpage. So, thanks to chatty.
