The basic features of their services do work - users are able to create their own apps and use Nexmo's services rather easily. Review collected by and hosted on G2.com.

Nexmo's so called 24/7 support is really bad. If you end up in a tight spot and need support during the weekends, you are really between a rock and a hard place. Our campaign halted for 3 hours during the most important day because Nexmo had put some restrictions to our account.

Nexmo is also becoming quite expensive to use. During our use of Nexmo the costs for making calls doubled.

Also, Nexmo has promised to get for example a quick and easy way to make our own "voice mail recordings" but at least in Finland you still have to use a TTS-announcement - which btw is not too good in Finnish. We also did not get a mobile number (we had to stick with a landline number) so we were not able to register that number and people we were calling were not able see who is trying to call them.

The SMS service is by far the easiest to use, simple API tools available, and priced very reasonably.

Documentation is complete, and they provide (nearly) everything you need to be fully self-managed. Review collected by and hosted on G2.com.

Recently, they've announced they will be charging to receive messages, not just renting virtual phone numbers and sending messages. To me that seems like double-dipping. The built in dashboard doesn't expose all the features the API allows, so you have to write your own for full access. Review collected by and hosted on G2.com.

Easier to use APIs with Shortnames. Transaction logs to track the success rate and failure rates. Data export available for all the delivered messages and transaction logs. Intuitive interface and comprehensive documentation in multiple languages. Comprehensive code samples are available in multiple languages. Review collected by and hosted on G2.com.

Some dashboards and reports could be improved. Additional dashboards should be included for additional information like distribution of message by telco vendors, invalid numbers, etc. Review collected by and hosted on G2.com.

I love the sleek, easy toned theme of the software, along with the simplistic home screen and displayed metrics that appears upon login. The landing page is not overly clustered, which is one pet peeve of mine when it comes to displaying navigation bars and customizable metrics. Review collected by and hosted on G2.com.

As far as I have seen, I have no dislikes to the software as of yet. Review collected by and hosted on G2.com.

We enjoy the APIs for sending SMS, tracking messages status and managing our numbers. Review collected by and hosted on G2.com.

Since we have to order in bulk and Nexmo needs to perform the order for us,I dislike that the numbers cannot be pre-configured with features such as callback type / number and webhook address.

Additionally Nexmo support is often slow to respond to issues and questions. Review collected by and hosted on G2.com.

It just works. Implementation was relatively easy. Review collected by and hosted on G2.com.

Definitely billing & payments. We can only pay 100 euros at a time, which in some short periods of the year is very low compared to our consumption, leading to multiple automatic reloads per day. This leads to dozens of 100-euro invoices, which only become available after quite some time, and which you cannot download, they can only be e-mailed to you. Impossible to know which ones you already have or not. Extremely unpractical for us. Review collected by and hosted on G2.com.

Nexmo has a great SDK that is easy to add to any project. If you need to quickly add SMS messaging to any site then nexmo is the ticket. I really like the price. For SMS messages they really do have the best deal out there. I liked how easy it was to get the first virtual number and then add more as we need them It's a super simple service.

BIG DISLIKE, they only have email support. If you have a problem or something that is mission-critical then you will be stuck waiting for emails. I would like to see phone support or at the very least chat support. Also, they are great until you have a problem. They do have enterprise support and maybe then you would get phone support. I would say support is not very startup or indie developer friendly. In the last few days, I have been working on a new project. I paid money for the nexmo service and they suspended my account I am working with them to get it restored. They said if might be a bug in their system. Review collected by and hosted on G2.com.

It's APIs are easy to use and set up. Low fees. Your own texting phone number for a low monthly fee. Logs for troubleshooting. Nexmo also offers voice messaging and other services. We only use the texting / SMS feature. Review collected by and hosted on G2.com.

This is an issue not about Nexmo itself but rather the mobile companies: There is a daily limit on how many messages you can send out per phone number. If you exceed this limit, then phone companies could block your number and you wouldn't be able to send out any messages! The limit seems to be 100 text messages per day, with some people suggesting it is less. This means you need to track how many messages you are sending out, and if it is more, you need to add new phone numbers and rotate the sending. Review collected by and hosted on G2.com.

I use Nexmo to send sms for notifications of a site we are very satisfied! Through Api it is very easy to use the SMS service completely customizable via the dashboard. Fast and functional it does its job well. Intuitive control panel. All the macro categories are well organized. Work in this way is facilitated. The documentation is well written. Customer service responds quickly. I have yet to try the voice service, but I'm sure it will be as good as the SMS service.

There is email notification when I am reaching the spending threshold. The Profile section is also well organized. The invoices can be downloaded after you make the recharge with paypal. I can add other users to my profile. There is also the possibility of using coupons to get discounts. In short, a complete service available to us. Nexmo works really well ! ! !

Nothing to say because I find a great product nexmo. Maybe I would raise the money loading fee for the account. Review collected by and hosted on G2.com.

Nexmo presents an easy and ready-to-use interface to quiklyset-up SMS exchange from internal platforms,without requiring lotof changes, even in legacy application.It has a clear and controllable pricing and fee policy that allows to easily and effectively control SMS management costs.

Usage of SMS outbound messaging during non working-hour (that is the case for business-critical application) is not properly handled, because delivery receipt does not means SMS received in the destination device, but only that SMS has beenaccepted by the last station to be delivered to the device and, outside extended working hours (from 9:00pm till 8:00am net morning, always during festivity), actually less than 5% of messages lands on destinatary device, despite 95%success decleard by reports.
