Yahoo mail in prijava prek gsm

Pozdravljeni!

Imam težavo, za katero ne najdem rešitve. Imam telefon Nokia asha 302 s katerim se prijavljam na svoj e-mail na yahoo-ju. Vendar mi vedno, ko se prijavim preko telefona, napiše tole:

we noticed an attempt to sign in to your Yahoo account from an unrecognized device in United States.

If this was you, please sign in from your regularly used device.
If you haven't recently signed in from an unrecognized device and believe someone may have accessed your account, please visit this link to change your password and update your account recovery information.
Thanks for taking these additional steps to keep your account safe.

Kje bi lahko bila težava? Telefon je kupljen pri telekomu, logiram se vedno iz slovenije.... zakaj mi javlja, da se poskušam logirati iz ZDA?!

Potem grem na računalnik, spremenim geslo in ista je potem preko računalnika OK. ampak takoj, ko grem spet preko telefona, je isto sranje.

Lahko kdo pomaga, prosim?
