I have been using this tattoo stick whenever my main internet is not working. I just load prepaid then transfer the sim card to the stick. It has been working good for the past weeks but suddenly the home page where I can manage the sim card's SMS, data transfer status, and most importantly the on/off of the internet. The last activity was I turned the internet connection off. Then right after that I couldn't access the home page ever again. I hope someone can help me.
