There have been some reviews for Acer Liquid E700 Trio who lit the device from all sides, so I do not want to repeat everything again. My impression is very positive. The smart phone is with me and my wife in everyday use with two mobile phone cards: 1x E Plus and Vodafone D2 1x - both of 1und1. In the combination, we have in our region better than average reception with extremely affordable prices. While the D2 charge card is part of the DSL flat rate package with 1und1 namely a flat rate on fixed networks, as well as a small 500MB Flatrate Internet, we can combine card so well with a 14,99Euro / AllnetFlat EPlus. The good standby time even with activated Bluetooth and WLAN convinced the possibility to use 3 SIM cards, which runs smoothly for me, convinced. After the initial 3 updates the device was completely stable, the display has a good resolution and high contrast, my BT headset, 2 AEG headphones and a Inatek-BT stereo box could be easily connect the wireless receiver is also quite good , the abundance of apps and the Android 4.4.2 surface are top. The smartphone is in addition to the call for music listening, on eBook reading, since it "is sufficiently large with 5, for news and movie playback at wait times, etc. Smaller weaknesses: The overall very comfortable acting camera that also with Microsoft -One Drive smoothly its images automatically Uploaded, has weaknesses in the image brilliance and in low light. For occasional snapshots and photographing documents, as a scanner for barcodes and QR codes but adequate. The non-illuminated basic function keys at the bottom are a blunder the designer, but bearable if you get used to it. The supplied headphones / headset is mediocre, but serviceable. I would forgive because of minor weaknesses 4,5Punkte if it were possible to find 4 but too little. The device is designed the price in my opinion excellent and not only as a starter instrument well, but partly because of the multi-SIM function in the business use.
