In short, to receive SMS alerts, your phone number needs to be formatted in the international E.164 standard. Additionally, to be 100% sure that alerts can be delivered to your phone, you can create a simple test alert.

Further on in this article, you will find more info about our SMS service, and a detailed explanation on how to format your phone number, create a test alert, track alerts delivery with logs.

SMS crypto alerts with a global reach

For SMS broadcasting, Coinwink uses Twilio API. Twilio is the global leader in SMS messaging and provides worldwide coverage for SMS delivery.

Our users come mostly from the US, Canada, UK, EU, Latin America, Asia, Australia, and other countries with well-established mobile network infrastructure. If the user enters the phone number correctly, and the phone is in range, during the three years of our partnership with Twilio, so far, we have a 100% SMS delivery rate.

In general, we provide global coverage and can deliver SMS messages to all countries. If you are living in a country where the mobile network infrastructure is not well-established, or your mobile carrier is known for blocking incoming messages, contact us before upgrading to Premium, so we can send you a test SMS alert.

Enter your phone number in international standard

The single most important requirement is to enter your phone number in the international E.164 standard.

The phone number should start with the plus sign, followed by the country code, area code, and then the actual phone number.

1. Plus (+) sign (replacing the International Call Prefix like 011)
2. International Country Calling code
3. Local Area code
4. Local Phone number

For example, here’s a UK-based number in standard local formatting:

Here’s the same phone number in E.164 formatting:

In a number of countries, local dialing may require the addition of a ‘0’ in front of the subscriber number. With E.164 formatting, this ‘0’ must usually be removed.

Receiving SMS alerts to the US phone numbers

Coinwink phone number from which we send SMS messages is located in the US, so it can deliver SMS messages to other US phone numbers formatted in both local and international standards.

This is an example cell number from New York, formatted in the local standard:

This is the same phone number formatted in the international standard:

Only for the US cell phone numbers, both formats are accepted. For all other countries, the phone number needs to be formatted in the international standard.

Track your activated alerts

If your phone number is entered in a wrong format, or entered incorrectly, our SMS service provider doesn’t know where to deliver the alert. The alert will be triggered (activated), but not delivered.

In such a case, immediately after the alert activation, you will receive an email from Coinwink about the undelivered alert with the link to this article. You need to enter your phone number correctly to receive SMS crypto alerts.

You can also track all your activated alerts, both delivered and undelivered, in your alert Logs, available in the Coinwink Manage Alerts window.

Send yourself a test alert

It is also a good practice to send yourself a test alert. If the test alert is received, you can be sure that the phone number is entered correctly and all future alerts will also be received.

For example, create an alert that will alert you when Bitcoin is above 10 USD. Because BTC is already above 10 USD, such an alert will be activated within 2 minutes, and if your number is entered correctly, you will receive the test alert to your mobile phone. In general, Coinwink SMS alerts are triggered every 2 minutes.

The Coinwink phone number

To stay productive when working or studying, some of our users put their phones to “Do not disturb” mode and exclude only the Coinwink phone number in order not to miss an important crypto alert. Some other users prefer to set a different sound for SMS messages coming from Coinwink.

Coinwink SMS alerts are always coming from the same phone number, so its receiving conditions can be easily customized on the user’s phone.

+16506677900 is the phone number from which you receive Coinwink SMS crypto alerts. It always stays the same.


Receiving SMS crypto alerts with Coinwink is really simple. Furthermore, because Coinwink is in partnership with Twilio, which is the global leader in SMS messaging, our crypto alerts delivery is fast, reliable, and has worldwide coverage.

The single most important thing is to enter your phone number in the international E.164 standard as described above. To be completely sure that SMS alerts will be delivered, send yourself a test alert.
