Cell-Fi Go

Telstra calls it WiFi Calling. That's how it shows up on my phone's menu.

BTW my phone is an import, a Samsung S7 originally with Taiwanese firmware. It had no VoLTE nor WiFi Calling, despite having the required hardware. I reflashed it with Telstra firmware (freely and legitimately available at Sammobile). This gave me the VoLTE and WiFi Calling. For all intents and purposes it is now a Telstra phone and has undergone two standard Over The Air updates with no problems.

Another BTW: I cannot get any support from Samsung Australia, even if paying retail service fees, eg for a proposed screen replacement. They always check serial numbers and IMEIs and from that instantly determine that it was not bought in Australia and equally instantly become disinterested in the conversation, almost to the point of rudeness.

Telstra is more helpful.

Frank, it's a piece of cake to replace a broken LCD screen on the Samsung.

All the components are just simply screwed and clipped together - if you can change a tyre, you can do it.

I've smashed the screen on both my earlier Note 3 and current Note 4. In the case of the Note 3, I made the mistake of buying a knock-off Chinese screen for it (from eBay).
While it fitted perfectly, the screen colours were washed out, as compared to the original genuine screen.

I sold the rebuilt Note 3 on eBay, and then bought a new Note 4 off eBay (Australian model).
After a few months, I managed to break the screen on that, too (despite a solid clip-on cover - they always manage to land face-down on sharp stones set in bitumen!)

For this repair, I purchased a genuine Samsung screen off eBay from a seller in Germany.
This screen performs like the original. There's only 9 screws and a heap of clipped-on components, to replace the screen, they're just so simple, designed for easy production line assembly.

Have a search of YouTube, there's plenty of instructive videos there.

The only thing I found, was that tiny screws and tiny components need good light, great care with all tiny screws and parts, and sometimes, a magnifying glass to see what you're doing.

If I was 50 yrs younger, I wouldn't even need glasses!

Cheers, Ron.

they are definately worth the money 100% . i have one in my car for work and can get reception basically in the area from paynes find east to leinster and down to kalgoorlie. The cel-fi paired with a cdq2197 rfi antenna i was able to call southern cross hospital while out neat the mt manning range. You obviously need some kind of signal but with the right antenna and right conditions you can get a huge range from an antenna.

Thanks Tony

We are looking for improved signal whilst in the car. In a Troopy, so wouldn't bother to try to talk on the fly, but stop and make calls. Also after Data when parked up and signal is week.

Cheers
