Question

Why are concatenated message sometimes slow to deliver?

Applies To

• Delivery Receipts
• Concatenated SMS

Answer

Each part of a concatenated message might take up to 10 seconds to be processed by the handset, and all parts of a multipart or long SMS need to have arrived before they can be reassembled by the handset. Hence handset delivery notifications for different parts of a multipart message might be delayed between each other, even though the messages are displayed at the same time on the handset.
