Hi,
AT&T and using the Eric. T62U. Battery life is poor. Are there
any experienced users who could suggest a longer living replacement
than the OEM?

Regarding the SIMM seating. I have occasional problems with the phone
not starting. If I open the SiMM carriage and reseat it, then the phone
starts. Not sure how it is coming loose (or even if that is the
problem), but looking for solutions. Many thanks for any help, suggestions.
