    Every text message can include up to:
  • cyrillic - 70 characters;;

If the message exceeds the mentioned numbers, it is automatically divided into parts, called large SMS. You pay separately for each part.

  • cyrillic - 67 characters;
  • latin - 153 characters.
(6 bytes are used to transfer technical information)

The mobile operators are not guaranteeing the delivery of large messages!

  • the recipient will not receive anything at all, but payment will be charged for each part of the message.

Question: What are the possible message statuses and what do they mean?


  • «Delivered» - is assigned to messages when an appropriate report is received from the operator's SMS center.
  • «Sent» - the message is sent to the mobile operator, but not delivered to the recipient, while its delivery time has not yet expired.
  • «Failed» - the message has been sent to the recipient that does not exist, he has been disconnected by the operator, he is blocked for receiving messages (the feature usually applies for the contracts), there are errors in the communication protocol between the recipient's terminal and the operator's base station.
  • «Expired» When you create an SMS campaign, you determine a timeframe for the message to be delivered to the recipient. If it fails during the specified period, it will get the proper status. The main reasons for failure - the recipient is out of network coverage or in roaming (abroad), either activated a call forwarding.
  • «Not enough funds» When you create an SMS campaign, the system verifies the balance for every single message. And if it appears your account has insufficient funds it will get the proper status.
  • «Stopped by user». You stopped the messaging.

Question: I have sent a message, the status shows it was delivered, but I didn't receive anything on my phone.

Answear: The status «delivered» will be assigned to the message after receiving an appropriate report from the operator's SMS center, so it can happen only if there are some bugs in the center.

    The message cannot be delivered to the recipient in cases as follows:
  • the phone is turned off;
  • the recipient is out of network coverage;
  • phone memory is full.

If the message will not be delivered in the specified timeframe, it will get the proper status «Expired».

Question: Why do some messages get the status «Not enough funds», while I have the necessary amount on my balance?

Answear: When you create an SMS campaign, the system verifies the balance. And if you top up your account after you composed it, the balance is not recosted. You need to enter into the report details and do the following operations: «Stop» the messaging and «Resume» it.

Then the system will recalculate the amount including your current balance, but only for those messages that previously had the status «Not enough funds». Then the messaging will be continued.
