I recently got this phone mainly for text messaging, and I love it for that. But I noticed early on that once the inbox gets to 100 messages, its always asking me to delete old messages in order to receive new ones, and likewise when I send them and the outbox has 100.

I have looked through the instruction manual and online, and haven't read anything about limits or how to change them. It can't really be that limited right? The phone has about 90% of its storage left still, as I dont use it for music or photos or gaming.

Any have or know how to fix this issue?

Any reply is greatly appreciated.
