This was exactly what i needed to get rid of my home telephone line that nobody uses anymore because of mobile phones. We only had a regular phone line because alarm equipment purposes. With this GSM gateway we save much money, because we could replace regular phone subscription with a prepaid subscription free sim-card. I just turned off pin-code on the sim-card by using a phone, and then put the sim-card in this GSM gateway. The date/year/clock was automatically adjusted by the GSM network. Nice external antenna with long cable give very good signal strength, but we are living near a base-station. Does not have to do anything with the configuration to meet my needs. The display show the number of the caller. When in standby it shows the date, signal strength and power-status. Nice product, and if you need a GSM to analog PSTN line, just buy this one! Thank you Banggood for a nice product!

Looks good though that there was no power supply in the box, but a contra plug. Manual very unclear .display badly read without backlighting. Would set the background lighting to color red/blue/green but unfortunately also not. Battery backup is also not present.Can't even get in, no valve or space for it. But despite that he works well. Caller id also work well, at the previous not.

Ziet er goed uit wel jammer dat er geen voeding in de doos zat,wel een contra stekker. Handleiding heel onduidelijk .display slecht te lezen zonder achtergrond verlichting. Zou de achtergrond verlichting op kleur rood/blauw/groen zetten maar helaas ook niet. Batterij backup is ook niet aanwezig.kan er ook niet eens in, geen klep of ruimte er voor. Maar ondanks dat werk hij goed. Caller id werk ook goed,bij de vorige niet.
