AM Internship Help

I have viewed the forums for a while now and have found great advice and would like to thank everyone who has contributed. I plan on contributing myself after I go through the internship application process.

Before i get into my questions id like to briefly introduce myself. I am a rising junior at a non-target (still top 100) with a 3.55 GPA where I am double majoring in fiance and real estate and I'm involved in a decent number of extra-curriculars with a leadership role in one of them. I currently have an internship at Morgan Stanley Wealth Management where I'm working with a couple of brokers. Last summer I interned with a local credit union. This fall i will be applying for various summer internships at banks and AM companies, mostly with a title along the lines of "Asset Management summer analyst" or "private banking summer analyst" or something to that effect.

-I am studying abroad this Fall, as most of the application should be submitted in September I am nervous about them contacting me. I will be back by early December so I don't think interviewing would be a problem, but I will not have my normal phone. So I was curious if will they email me(which is fine)? or try and call me(in which case i would be screwed)?

-How much will my MSWM internship actually help? Do I have a legitimate shot at not getting rejected straight away and making the interview stage from a BB or a decent AM firm (like a Northern Trust or BlackRock for example)? I am pretty much relying on the online application plus 1 pretty good connection at BNY Mellon, as a couple BBs recruit at my school, but only for operations.

-Lastly, before i take off for Europe, id like to do a little networking with alumni on linkedin. Should I stick with only trying to contact alumni working in the department that I want, which is not many, or contact them regardless of their department, as long as its a company im applying for? Also, could I just get some general tips on how to do this from someone with expierence, like what to say?,should I ask to meet or just for advice? etc...

Thanks in advance.

PS: I posted this in another section, but I'm guessing from the lack of response that I got I may have put it in the wrong section, and I am thinking this could be more appropriate. Sorry for being repetitive, I will delete the other thread I started tomorrow if there is still nothing.
