Hi I’m trying to download the republic app onto my Galaxy J3 samsung phone but it’s saying that the sim card is invalid. It’s a republic sim card so I don’t understand the problem.
Have you tried reseating the SIM card to make sure it is inserted correctly? Is the phone itself giving you that message or the Republic App? Additionally, is this a new SIM? You may want to take a look at this thread: Invalid sim card error message? .
If the J3 was not purchased from R.W, is it the correct model and build number supported on R.W Supported phones ?
For the Samsung Galaxy J3
