Hi Petros,
I have dealt with this in the past, and resolved this by putting the
modem into PDU mode and sending / receiving messages in this way. PDU is
essentially a 7-bit binary mode operation of a GSM modem.
Information on PDU can be found at:

Hi all
I use the synaser unit to send automated SMS messages from a service
application. I have tried this with SendString and ATcommand. In both
cases the received SMS message occasionally lack the first few characters.
For example:
sBlock.SendString('AT+CMGS="' + GSMaddress + '"'+ #$0D);
sleep(50);
sBlock.SendString('abcdefg 12345' + #$1A);
sleep(200);
may astually transmit 'cdefg 12345' to GSMaddress. I cannot find a
patern as to how often this occurs and how many characters get truncated.
Has anyone ever dealt with this one?
Many thanks
Petros
