I am trying to send SMS to the people all over the world using a non-registered short codes, but the sms cannot be delivered to US or Canada. How do I achieve this?
Is there an API to get information of the country using a phone number, so that I can know if the current number is of US or Canada's?
(Disclaimer: I work at Nexmo.)
To identify US vs CA numbers you can use Nexmo's Number Insight API. Besides the country you can also get lots of info, landline or mobile, carrier, reachable or not, etc.
If you you want to send to the US using short codes without needing a short code yourself, you can also use our US Short Codes API. If your use case fits into what we support (two-factor authentication, alerts, or marketing).

I wanted to build a web-based system using which you will come to know whether the mobile number is registered with WhatsApp or not? It's just to check whether the number entered in textbox have WhatsApp account or not?
I tried finding resources regarding the same but unable to get any solution on it, please share some link for reference so, I can implement it and get to the final result.
You can use the Whatsapp API through Wassenger of Waboxap to send a text message and via webhook service like Loggly determine if the message was delivered. The person will however get a message, which might cause them to block you.
Here is what I am looking to setup & I'm wondering if it is possible:
I have a classified ads site where people can join the site and then are allowed the ability to email any listing. I would like to add the ability for people to text message listings as well.
Listing owners would add their cell numbers if they would like to be contacted via text message, the site would then allow user to text BUT it would not show real phone numbers, each listing owner would be assigned a nexmo number and if they choose to give out their phone numbers, they can.
Then, I would also like the ability to send out a general broadcast to all users. Is this possible? And, if so, how would I integrate something like this?
Yep all of that is possible with Nexmo you seem to have 3 or 4 separate use cases here so lets break those down:
When your users sign up for your site you'll want to capture their Cell numbers against their account, you might want to use the Nexmo Verify product as part of that signup to ensure you have a correct and valid mobile number.
For users to be able to add listing via text you would need to get a nexmo number for them to send their listing to, that would be one number for the whole site and you could look at the senders number to link the message to an account (from the one you captured at registration) If you don't recognise the sender of a listing message then you'll want to send back some kind of response asking them to register and a link.
For buyers to contact sellers without revealing their numbers this is a very common use case called 'Message (or Call) Proxy' you need to rent a number for each seller (or listing) so you'll need to factor that into your pricing, then you forward any messages sent to the number to the seller, you will also have to implement some logic to handle replies and track state in your application, within SMS there is no concept of a reply so each message has no association with the previous one, this is a bit tricky when you have several conversations going on over the same number.
Finally the 'broadcast' this would just be a case of iterating over the list of numbers you have for your users and sending the message to each one, you will need to ensure that you comply with any regulations around sending of bulk messages in the country you are sending to, more details for that are on the nexmo knowledgebase https://help.nexmo.com/hc/en-us
We have a sensitive service and only want one sign up per person, more or less. We require phone number verification when signing up. Looking into people we've caught creating multiple accounts we see they use twilio numbers, but this is a manual process of looking up the carrier, etc. etc.
Is there a way to automate this and block twilio numbers? I know craigslist and gmail are able to do this, but I'm not sure how.
Thanks.
Twilio developer evangelist here.
You can use the Lookups API to check carrier details about a phone number. Carrier details will include whether Twilio is the carrier.
Let me know if this helps at all.
I am working on an eCommerce website but our client told us to add functionalists like they want to verify an user account by sms or by call.
I don't know how to do this and how many of websites and apps do this.
Do they use any third party services or can we implement it by our won?
If we have to use this service please tell me the name and how much it costs and how to setup?
If there is any alternative please tell em that also.
Moreover I want to use this services for testing also.
Any help would be appreciated.
Some websites/apps build it themselves with SMS / Voice APIs...
Others use a Verification specific API...
With SMS / Voice APIs
You'll need to generate a code
Send it via the channel you use primarily
Set some kind of time delay job (queue, worker, whatever)
Send a fallback message should you get no response from the user
With an SMS API, that likely varies per country,there is a solution that allows you to go globally with an API call for a flat fee of 10 cents per verification, NOT per attempt (unsuccessful attempts will not be charged towards your account)
Nexmo’s Verify API
Make a call to https://api.nexmo.com/verify/json (or /xml)
Add parameters: api_key, api_secret, verified number, brand
Optional parameters: language, length
Take a look at the Nexmo's Verify documentation here!
Verification code should arrive to your phone as an SMS. If you wait a while, you'll also get a phone call, and the code will be read to you. The timing and channels used depends on the type of number, the country, and the carrier.
Reasons to implement Nexmo's Verify
Landline & Mobile Verification
Failover & Retry Sequences
Simplicity.. Just make one API call
Other alternatives: Enterprises (sign a heavy/clunky contract)
Full disclosure, I work at Nexmo
My idea is to make an application start automatically when a message from a specific user reaches the inbox of the mobile . For example if my friend sends some numbers to my mobile, the sms has to be read and validated first and then calculator ( inbuilt mobile application) has to be triggered and process the numbers from the message. Please help me with the above query.
I am far from convinced you will be able to give the phone user access to the same sms you use to launch your MIDlet.
You may need to use native development on the phones that support it if J2ME can't give you exactly what you need.
In any case, you probably want to try with J2ME first so you need to read the specifications for JSR-118 and its PushRegistry API, along with JSR-120, which interfaces with SMS.
Most current J2ME-enabled phones will support static SMS Push but you will need to send the SMS to a particular port, much like you would data over a standard library socket.
I don't think you can trigger on just any old SMS message arriving.
This is the class you want to look at, in any case:
javax.microedition.io.PushRegistry
