I've had a pair of G3's for a little over a year now and they've been fantastic on every international trip we've taken. In my review of the G3, I mentioned that the device is quite bulky and heavy due to its large battery and ability (which we never used) to serve as a portable battery for mobile devices. Even after a full 8-10 hour workday, we rarely saw the battery level drop below 70-75%. I think GlocalMe has greatly improved the form factor of the device. It has a much larger screen, is much thinner and weighs a lot less. The battery is smaller (3900mAh vs. 5350mAh), but that wasn't an issue for us. Even after a full day of use, the G4's battery was still around 40-50%, so I think it could easily last two days. G3: 126mm x 64mm x 17mm (thickness); 235g; 5350mAh G4: 136mm x 71mm x 12mm (thick); 187g; 3900 mAh I'm not sure about the CPU/RAM specs, but the G4 boots faster and the UI is faster than the G3. The screen is of a similar resolution (perhaps a bit higher, but not noticeably higher), but I've found that the colors look more vibrant and the contrast is much better. I last updated my G3 software a few months ago, so it may be outdated, but the G4 has additional apps: Google Maps, a translation app, and a currency converter app (although it appears to be entirely in Chinese). Map integration is great and overall I hope we can install our own Android apps on the device in the future! I would also like to share some of the things that I think could be improved or that are considered to be the G4's shortcomings. Let's start with the obvious: since the device is so new there aren't any case options for it - hopefully that will change soon. Another major disadvantage is that one GlocalMe account cannot register multiple devices. That means you'll need multiple email addresses if you have multiple devices - I don't think this is a problem in general, but for those of you moving from the G3 to the G4 it can be a little frustrating . Another consequence of this is that accounts (and therefore devices) cannot share purchased plans. I hope this is something they will improve in the future. Finally, I noticed that data plan storage now includes unlimited plans for specific regions that throttle after a certain data limit is reached. This is a great and inexpensive option for many if you don't plan on using a lot of data or if speed isn't a big concern for you. In Brazil, for example, the unlimited plan was $5 per day, while the data plans were expensive in comparison: $10 for 1GB or $26 for 3GB, although of course there's no throttling on those plans. Nice to see GlocalMe adding new plans for different usage profiles! In summary, we have had GlocalMe devices on 6 international trips and they have worked flawlessly. No problems registering on local networks or using GlocalMe plans. The hardware is solid - we've never encountered an issue that would have required a device reboot. Finally the software is usable and there have been many improvements from the G3 to the G4 which hopefully is a sign of many more improvements to come. If you travel a lot and want a cheap and reliable solution to access the internet abroad, I recommend the GlocalMe G4!
