Plus Keyboard

Cell phones were designed for calls, not messaging. Hence, earlier design engineers tried appending old mobile phones with keypads to make texting more feasible. Ericsson made great efforts to turn a regular mobile into a messaging cell phone, but the results could have been more desirable. 

We wonder how a person carried this phone in their pocket. Even if the keypad were removable, it wouldn’t improve the design. Having an external keypad and attaching it to the mobile phone whenever you need to text is more inconvenient.
