Is it possible to add a signature file to text messages?
You use signatures on an SMS if you use an app that supports adding signatures automatically, like Handcent or Go SMS Pro.
Bear in mind that the .sig would cut into the 140char limit for SMS.
Thanks my old phone had the capacity I am just surprised a smart phone does not have that capability!
Modern smart phones do have that capability, BUT it's the 20+ year old GSM network technology itself that limits SMS to 140 characters.
You can indeed send messages longer than 140 chars. But what's actually happening the phone is dividing the long message into 140 char chunks. So you enter say a 200 char message, your phone divides it into separate 140 char + 60 char chunks, sends it as two separate SMSs, recipient's phone concatenates the two SMSs into a single seamless 200 char message. Of course you are billed for two separate SMSs by the carrier.
I think the OP meant s/he was surprised the smartphone SMS app didn't have the sig built in. The counterargument is that smartphones are designed to allow 3rd-party apps to extend basic functionality.
On both ends.
I've given up on straight SMS; I use Google Voice (both through the Voice app and using the SMS-email functionality).
I can't see signature bottom in my User CP section. So how I add text message signature
It's certainly a bummer if the recipient is getting charged double, because a sender's (probably) useless sig made the message longer than 140 chars.
Open text message app. Go to settings. Scroll down to Signature Settings. Edit Signature and add or delete a signature. Uncheck Add Signature.
I was able to initially setup a signature on a Nexus S ver 4.1.2 (Samsung) but made an error in the phone number and have not been able to change it since.
I waited to upgrade and now have a Samsung Galaxy S version 4.2.2 hoping I would be able to update the number then but the old number still shows and still do not know how to change it.
I should add that the signature settings only allows me to add my name. I am thinking the issue might be with Google since the same error appeared on the S4 as was in the Nexus S.
When you update you need to do a factory data reset that will clear any old data errors and all will be straight .
Separate names with a comma.
