Sign up for 25 cent per minute plan for new prepaid line

You can’t. The 25 cent per minuteplan was discontinued in January. It is no longer available.

I am living in the US only a few months per year. In the last years I always changed to the pay per minute plan during my absence and to a monthly plan, when I am here. 
What do you suggest to me what to do?

@Joe48 There is simply no way to avoid paying for a plan you can’t use while you are gone. There are ways to keep your account open and minimize how much you pay while you are gone but you can’t avoid paying for a plan at some point. If it is important to keep your number, you can either port it to google voice and just get a new prepaid number when you visit or port it to some number parking service and port it back each time you come to the US. Another option is to port your number to some other prepaid service that will let you suspend payment while gone, if they even exist.

Threre are MVNOs that use the ATT network that offer PPU.  At a lower cost too.

Thanks for your help! Any MVNO recommended especially for Alaska?

The one time I was in Alaska, I was still on ATT Postpaid, and being very careful that the phone didn't connect to the Ship's system or to Canadian Towers when on excursions.  If want some plan choices that run on ATT's network but aren't offered by ATT and ATT Prepaid, there are many out there.  Ones offering PPU are limited, the last time I had one was H2O Wireless, which was $0.05/minute and I made sure I didn't use data since on smart phones, if data is enabled, can very easily get expensive on PPU plans.
