No bars when inserting new ATT tablet sim

[samflanders]

I just got a Straight Talk "Bring You Own Tablet" sim card kit containing 4 sim cards (2 t-mobile, 2 att). When putting the nano sim cards in my Ipad mini with LTE, I get no signal bars for ATT or T-mobile even though both carriers have a strong signal at my location. Instead there is just an "X" showing no service. I have not yet activated any of these sims to a Straight Talk tablet plan. With most other carriers, I get a signal even before activation of the sim. Is the situation different for Straight Talk in that I need to add a plan to see signal bars??

Hi samflanders! No, signal bars should be showing even if there's no plan added yet. Please check your forum inbox for the private message that I've sent and we will further assist you. Thanks!
