Unfortunately, as with so many, for me too little reception inside of rooms, where it yet with any device and SIM itself - have been difficulties (A1 Austria). The wireless coverage at the place of residence (rural areas) was insufficient. In the workplace (urban area), there was also at the reception with the L5 II no problems. Have the phone sent back and because it gave me basically (service, voice quality, Internet) really liked, exchanged for a LG Optimus L7 II. This unit has now very good, at least in the G2 network coverage. The signal strength or rather weakness was also measured by the test so connect.de - see reviews (transmission and reception quality rating - compared L5 / L7). Since I use the phone mainly for calls, SMS and WI Fi, the L7 II is sufficient for me. The endurance of the battery is excellent especially when L7 II. Conclusion: the end good - everything well, thanks to Amazon !!
