Repercussions of quitting job during probation period in Abu Dhabi?

Hi Guys. Need your advice on something that has been bothering me for last few days. I completed my first 15 days in Abu Dhabi today. I am from outside of UAE & came here to join one of the largest bank in UAE..After joining the position here and working for a few days i realized the role is different from what was explained to me verbally during the interviews. This requires one particular skill extensively which i had very little experience on and used very little in my previous roles.Also investing time on this skill will not help me in future beyond this organization in my career progression. So want to know what could be the repercussions if i look for another job here and get an offer from some other organizations.

i) My visa stamping/ emirates ID / Insurance are work in progress
ii) My offer letter and the labor ministry document says " either party can terminate the contract without notice within the probation period " ( Which is between 3-6 months )
iii)I am expecting my line manager not to be cordial if i break the news to him.

Awaiting your response.
