You can send an SMS message to any mobile phone on a GSM network. Please note that many US cellphone providers are now blocking all SMS messages from external gateways. We're not sure if this is a short term or long term issue, but if you want to send SMS messages to a US phone. Unfortunately there is not much we can do about this as this is a policy of the recipient network.

Either you can send it through our website or you can send SMS messages much like you do a regular email. Simply address a new message to @smsgateway.com, replacing with the telephone number of the mobile phone to which you wish to send. You will need to include the country and area codes in the number. Hyphens can be included for readability, but are optional. For example: 1-555-123-1234@sms - US destination 61-412-123-123@sms - Australia destination 44-7912-123-123@sms - UK destination In the above examples, the hyphens have been added for ease of reading, but are not required. See this link for a list of country destination codes

An SMS can be a maximum of 160 characters. This is a limitation of SMS, and not a restriction at our end. If you try and send an SMS longer than this, only the first 160 characters will be sent.

There are many possible reasons for this. The SMS may be delayed in some system along the way, and may be delivered shortly. There may be some routing problem between the SMS providers. The receipient network may be blocking and dropping external messages. The moon may be in the wrong phase! Unfortunately, SMS is not an entirely reliable transport system. Generally what we've found is that if sending to a particular number works the first time (eg. a particular user on a particular network), then it's pretty reliable. If sending to a number doesn't seem to work, then it's probably some sort of network inteconnect/blocking problem, and there's not much we can do. Still, there aren't any guarantees, and we've tried to provide you as much information as possible.
