Special characters are wrongly coming in SMS

[Anoop]

Hello all,

When I try to send an SMS to a real SMSC, some special
characters are
coming wrongly.
eg.
if i try to send a message '@java', the message reaches mobile as
'ijava'

In my application logs, I can see that i m sending as '@java' only.

What may be the problem here.

Thanks in advance,

Best Regards,
Anoop

Hello,

encoding is the problem, try to use this in your code to encode the
message before sending:

Problem is from the smsc just try to send all the characters in one go and figure out wat characters replace each other . And replace the correct characters and send it
Thats how we handle .

So incase of @ it is being replaced by i
so figure out wat characters need to be sent to get @ and replace accordingly in u r message String .

One more way to fix it is asking u r smsc operator to fix this issue .

I had the same issue and encoding conversion fixed the problem, I
guess it is not SMSC issue.

Hello,

According to ETSI GSM 03.38, '@' is included in GSM character set. It
is mentioned that no
special Unicode encoding is required for these characters.

In this case, is it really required to encode the message.
I think unicode encoding is used when we are sending multilangual
SMS..

Sure, you can encode this in Unicode (UTF-16BE) and it will work, but you will have to encode all your characters in unicode so you will lose characters per message because of more space needed for such characters. I say you can do it in GSM 03.38, I did it.

I tried another way out.

i changed my application's data encoding scheme to ASCII(IA5 (CCITT T.
50)/ASCII (ANSI X3.4) in smpp.pdf) in a test code which doesn't use
JSMPP stack
Then i could see that special characters are received properly.
Earlier , the test code was also giving wrong output for special
characters when SMSC default alphabet coding scheme is used.

What may be the reason for this

Probably i could not check this with JSMPP as it didn't have an enum
value for ASCII coding.
(Alphabet ). Any reason why the other data coding schemes are ignored
