Very good. Recommended.

I'm using 1S2U service for my education company for past one year. A great all in one SMS solution which make our job easier to communicate with students.

i am sending messages through 1s2u.com since 7 months and their prices are more than cheaper than my expectations. really awesome service and best competitive prices in bulksms. thanks to 1s2u

The German route is not working since September 2019. I asked a few times (today is 31.01.2020) when it would be functional again and every time I got the answer: "we will send you a email when it will operate again". With this kind of service and support is impossible to plan a business...

Really Awesome Services... Best in support and sms service overall.

At initial level there are some issue but support team form 1s2u take this issue on extreme priority basis and resolve this immediately. Thanks to the 1s2u team for your extended help. Right now I didn’t any issuers.

It does not work, have many times trouble and problems, sms are not delivered even though they say the have. Have tested it many times, they never admit their lack of service. Totally unreliable. Stay AWAY

After months of using i experienced possibly the best customer service of all time. with their sms and HLR services, i have satisfied much better than other bulksms services available. also they provide sms verification services which is best for verify all applications. worth for money...

We have been part of this 1s2u for 1.5 to 2 years, at present we are sending 1 million to 4 million messages a month while not major issues. we personally suggest to all of you use 1s2u.com if you are looking for best service and competitive prices. support team is always available! good luck!

I am here to share my good experience. I am the customer of 1s2u.com. Their service and the price are attractive with good delivery rate. Last week I sent some bulk files and most of them never reached. I have sent in a wrong format and consulted support team and they explained me what was my mistake and they credited back 50% sms into my account. That was awesome service i never found.
