How to insert your sim card into the Wattics Octopus GPRS Gateway

First of all, you must ensure that you use a standard sim card, with the 4-digit PIN code disabled (that can be done with any unlocked mobile phone). Other sim card types are not supported.


The sim card must be inserted as follows.


When you push the sim in, it should stop itself with 5mm of the sim card remaining outside of the Octopus, allowing you to remove it easily. There is no release mechanism, just push and remove.
