Why did Warren need to invent communication lacrimas?


When members of fairy tail were traveling to defend magic council members they
were communicating through lacrimas to the guild, and during the Phantom Lord
arc Mira used a lacrima to contact Laxus, so why did they need to "invent"
what were basically cell phones when they already had lacrimas to communicate
over long distances.




A reason could be that the usual
[Lacrima](https://fairytail.fandom.com/wiki/Lacrima) crystal, which is shaped
like a crystal ball, looks a bit bulky. [![enter image description

**Why did they need to "invent" what were basically cell phones when they

Communication Lacrima invented by Warren which, as you pointed out, is shaped
like cell phones are much smaller in size but has the same functionality.
**This makes it easier to carry around.**
