    Dropped Calls Caused By Defective SIM Card

    As of recent I've been having a lot of dropped calls. The dropped calls issue occurs frequently with-in a few seconds/minutes after connecting the call. Sometimes the call would drop during the connection process after the number has been dialed. What is strange about this issue is the phone would have fairly good reception (almost full bars) and out of no where, lose the signal followed by dropping the call. Within seconds to minutes, the phone would pick-up the signal again with full bars.

    I've tried several phones (Nexus one, N900, Huawei) on Wind with the same result. I was pretty much convinced it was network issues. As a last attempt to troubleshoot the issue, I tried an Wind sim from another subscriber in one of my phones and did not notice any dropped calls. I immediately drove to a Wind/blockbuster store to swap the sim. Since the sim swap, I haven't had any dropped calls in areas with strong coverage leaving me to believe the sim card I originally had was defective.

    Just curious if anyone else experienced this?

    happened to me a few weeks back.. couldnt figure out what was causing this until i took my sim out and reinserted and it gave me SOS mode. Took it to the wind store they replaced it and the guy told me it had happened quite a bit

    Yup if you are witnessing dropped calls or bad speech quality such as what beer wisdom is witnessing have your SIM swapped out because their is an issue with your current SIM. Wind has changed the vendor that supplies them SIMS now.

    THANK YOU for posting this. I've been living with dropped calls for weeks and was getting frustrated. I will try a SIM swap.

    Could this bad SIM issue have been the main reason for the dropped call issue over the last six months?

    If so why has WIND not make it public and avoid all the bad PR?

    I encountered Bad SIMs more than you would think. I had a user that had issues calling to the US, swapped the SIM and calls worked fine. You'd be surprised what swapping a sim can fix.

    Anybody with a bad SIM want to post their SIM numbers? Maybe leave out the last digit.

    I think it's safe to assume all WIND SIMs will start with that. The next set of numbers are more important. I've got:

    89302 49010 00153 XXXX - USB
    89302 49010 00114 XXXX - phone

    Neither one has any problems.

    Since the Sim swap, the experience has been much more pleasant. Dropped calls have been minimized.

    I actually wrote down the number to my bad sim card before the swap:
    89302 49010 00098 XXXX

    Minimized but not solved? The SIM issue has been an interesting one. I know of several people here in the office looking for a cheap cell pkg that have dome multiple SIM swaps and still nothing. It stars off better but still the issue of dropped calls. To be fair they are used to almost perfect service from their old carriers.

    at lunch today we got to talking and it struck me in 10 years I have called into Rogers maybe 5 times.. a Women that has Wind said in the last month she has surpassed me many many times over in calls. How often have you called in?

    also was the 911 issue ever solved? I had posted that question on the wind forum and it was deleted..

    Imo "minimized" is probably as good as its going to get with any mobile phone service. Just for comparison, I experienced at least one dropped call every few days on the Bell/Telus HSPA network. Most of my dropped calls on Wind just happened to be corrected by replacing a faulty sim card. I haven't experienced a dropped call for over a day(since the sim card swap) which is a significant improvement. I'm sure dropped calls will be inevitable in weak coverage areas.
