So, after 2 years of using a Verizon sim card with my Linksys WRT1900ACS and Sierra Wireless MC7455 modem, it will no longer connect/register to the 4g network and I get an email from Verizon with this message:
“Someone on your account has switched from the Samsung to the by moving SIM cards. This change, however, will not work because the SIM is on an unlimited plan and incompatible with . We recommend replacing the SIM in the original or other compatible device.”
Does this mean my journey to have a 4G router on my Verizon unlimited plan has come to an end? I’ve tried everything I know to get it to work again (which actually isn’t much). Has Verizon cracked down this much and I won’t be able to get it to connect anymore? Not sure where to go from here except to cancel this line of service and sell the equipment. Has anyone else run into this?
This sounds strange. Have you removed a word there? Anyway, I suppose they checked the IMEI and saw that it’s not a Samsung device. I don’t know if it’s possible to change the IMEI on a MC7455. Some Huawei sticks are capable of doing that.
I had the Sim activated in a Note 3 and then just switched the SIM to the MC7455 so does it even see the IMEI on the MC7455? As soon as I put the Sim back into the Note 3 everything works fine.
The message from Verizon is weird, but that’s exactly how I received it. Wherever there’s a blank and seems like something is missing I guess technically that’s where it would say mc7455.
I never changed anything. It just one day quit working and I haven’t been able to get it to connect and register on Verizon’s Network since.
It is in MBIM mode. I received instructions on here to set it up that way as I couldn’t get it to work on my own. If you can provide new instructions to set it up a better way I will definitely try that. Otherwise, I may have to declare this project officially dead and drop this line of service with Verizon.
The OpenWRT router you are using and facing the problem of connectivity. The main issue behind this problem is the software of your device not properly updated. SO I suggest you check the system update first then after that go for the iTunes if you are using because many times this problem also occurs for iTunes’ log file if this problem occurs then go through https://itunessupport.org/blog/why-cant-install-itunes-on-windows-10/ for the best solution.
