[easyt]

ok soooo
both me and partner been with virgin mobile for yearsssssssssssss
both recently got new handsets
mine a lumia 620 (3/4 months ago)
mrs a lumia 720 (2/3 months ago)
i work from home and for a few weeks now ive been having sporadic signal(been fine for over 5 years over 4 bars) always
anyway everytime i pick my handset up its showing no signal but when i try to use it all of a sudden i have 4 bars
customers are phoning my landline saying my mobile goes right to answering machine

my mrs phone is fine when shes at work but does the same when she is at home too

tech guy on phone first said it was my handset.......when i mentioned my mrs phone does the same and is a different model he then said oh then its your sim cards ill send you both new sim cards
..................am i being fobbed off here?

i dont see how it could be the handset then the sim card?
he also mentioned ee? im on virgin that uses tmobile whats ee got to do with anything?

all ideas / help appreciated
