Note on Refurbished Modules:
As you may have noticed, the SIMCom modules used on these breakout boards are classified as refurbished. What this ultimately means is that the modules have been de-soldered from another device that may or may not have been in operation, and re-soldered onto the brand new breakout boards with the rest of the components being brand new as well. The modules are still fully operational and original SIMCom modules, but may have some marks and scratches on their labels (This happens during de-soldering). Any similar SIMCom module sold at this price point will almost always be using a refurbished module. Some manufacturers have even gone to the lengths of reprinting the module label so that they seem new, but if you look closely you should be able to see the original label underneath. We would like to be completely transparent regarding all the items we sell which is why we think it is important that we explain the above in such detail.

That being said, every SIMCom board we sell has undergone some basic quality control before we make them available to our customers. This includes a visual inspection, firmware re-flash to the above mentioned version, and a simple network registration check.
