Comments on GSM Modem (SMS) for Android

★★★★★ Great app. I was able to send sms to multiple numbers. But I can only send 60 characters per message. Should use GSM-7 encoding.

★★★★★ Dear sir, You did good job, Support for many people. How to get sent message by variable? So we will get sent message by variable then we will redirect this page to other page to complete process. Thanks Dear sir, Thank you for reply. The message was sent by get method url. The sms sent message result is also same url. Is it possible to provide, the scent sms message result is another url by same get method? Thanks

★★★★★ It's so good. But can you Please make it for 2 sim connection? Its only send sms from one sim. But Android have 2 sim card slot.

★★☆☆☆ It reboots my GSM tabled. Tablet has android 7. Please advise.

★★☆☆☆ I'm giving u one star because there are so many apps like this already I'll rate you 5 stars and can pay if You can build an app like this which would work from live server in Pakistan

★★☆☆☆ This app tries to get around google play security by being a front for the "real" app which it requires you to download from outside google play. Hard to trust this.

★★☆☆☆ Work only, when mobile is connected to Wi-Fi. While using mobile data it shows error, unable to connect network. Why it is not working without Wi-Fi network?
