I have a problem with 6230i. I can send network request let say for checking the credit for my card. It works, but when I try to call any number it always gives me busy signal.
I fullerased it, wrote mcu+ppm+cnt, then pm, and after did ui settings, full factory etc.
Is it hardware problem or something else.
I tried it with other sim card, the problem is not in sim card.
Thanks
