How long is the battery life on the Samsung Slyde m540?

The Samsung Slyde m540 was first released on September 10, 2008.

There is no setting on the Samsung Slyde m540 to increase character limit for text messages. Upon doing some searches online, I found out that others have also experienced the same issue. Someone mentioned he had a limit of 139 and someone else said he had 150. But a user from a forum said he was able to send a message with 1000 characters. So I guess there must be something wrong with your unit. I suggest you have it checked with an authorized Samsung repair center or the store you purchased it from.

I find the same problem usually after 100 characters. It's very annoying. It will send larger items as a picture message.

It doesn't have a SIM card slot because it's a CDMA phone.

To turn it on, press and hold the End key for two seconds.
