I am a westerner who will be visiting the area for about 5 days for work. I have gotten my work visa / travel visa approved and printed out the official document. I have a few questions below and any help is appreciated! Apologies if they seem a bit naive.

- I have Verizon and apparently the connectvity and cell service is highly covered. I will be using Uber often, will this be a problem with my american phone number? Should I get an ESim even though verizon covers me?

- I have heard uber drivers will attempt to haggle in the car / en route, is that common? I dont mind haggling, but not sure customs and or wanting to offend anyone.

- I am getting HEP A, B shots as well as diphtheria . Any others you all recc?

- I am staying at the Westin Mindspace and traveling daily to the Argus Knowledge City. It looks to be about a 12 minute walk...I am a pretty big guy, muscular, not sure if it would be safe to travel during the day / get hassled?

- Are stray dogs a big issue in HYD? I have heard that rabies is still a big problem with dogs in India but curious here if thats an issue?

- Finally, Ill have one day to myself...any options for something interesting? (Historic sites or shopping? Bare in mind, ill be using uber) I would like to grab a piece of local made pottery, not sure where, along with buying myself an India cricket jersey.

- Is HYD/IND a cash heavy society or is card common?
