Replacement 4G Module Card for Dell DW5811e for QualcommEM7455 4G WWAN Card LTE NGFF Card Module Wireless

Was skeptical this would work but Dell refuses to sell these standalone, even as a replacement for a broken one. Swapped my broken one out, entered the new IMEI and Verizon activated it no problem.

I purchased 5 of these in May that are all defective. I bought of the same model earlier in the year that worked OK. None of the recent batch work. I substituted them in place of the working system and the new cards don't work. I checked the firmware and it was not the same for all five but one had the same firmware version as the prior card I bought that is working but the new card does not. Unfortunately, I did not test these when they arrived and Amazon won't let me return. Total scrap.
