Number Ported but Phone still using assigned number

[SuperOma]

We ported over 4 accounts yesterday and 3 of them went fairly easily.

The fourth is having an issue. The number was ported, the PM account profile shows the ported number, but the iphone will not switch back to the ported number. 

Help please!

[SuperOma]

Yes thanks.

HI @SuperOma  so, all 4 are good now?

[SuperOma]

Wow, thanks. We did that yesterday and all seemed well, but today it reverted. Thank you for your help and quick response. Much appreciated

@SuperOma 

put the old sim back in that phone and when it stops working...then install the new PM sim.
