need some advice please.

I keep on getting banned on my current phone with instagram( don't know if they detect the sim card or something on my phone and ban me immediately once I login).I will not be buying proxies, because I need to reply to my customer the reason I won't be buying proxies is because when jarvee is doing its job following with a proxy I also need to occasionally reply to customers through my phone wherever I am so if I switch between two proxies I think that will make me look bad in the eyes of instagram, not sure do.

PLAN:
so my expensive plan is to get 2 more cheap smart phones that can run instagram and to manage 5 on each phone so 15 in total spread over 3 smartphones including my current plan with new unlimited 4g sim plans

QUESTION:
1.I have a worry about my current phone that is: if I buy a new sim for it that allows me to access the internet, that instagram still detects something in my phone and that this will lead to a ban. I think that my phone has been flagged, again not sure if its my phone or the sim card or my wifi. bytheway I have been using jarvee through my wifi so it could also be the wifi.

2.and also how can I use my phones proxies trough jarvee? because I don't want it too connect to my wifi because everytime I do that I get a ban or pv.

Question 1.) Yes, instagram has your device ID information saved, and if you have abused it will be marked as flagged. You can change the Device ID with rooted tools. But info can still leak. Best bet is to not use that phone for IG anymore. Use the other 2 that you will acquire and do not connect to your local network. Or sign in on accounts that are/were on your local network.

Question 2.) You can setup a tunnel, so that you can connect to your phone mobile 4g network as a proxy. There are plenty of people here who can setup you up with this. I have come across it in some Signatures.

That is a very bulletproof method. Tunneling to your mobile 4g network and keeping a physical device to sign in on the account with. So that you never have to use the embedded browser.

How to fix login block?
My account was disabled by mistake and I requested to IG a reactivation. Now my account is actived but I can't login.
I tried all methods... I changed devices, wifi, proxies, IP.
Nothing works. When I tried to add my ig account to fb manager says your IG is blocked go to app or browser to solve your problem.
Also, I talked with fb support and they answered my account is active so I should access without any problem, but I can't login.
Please help me

Each phone = Different connection = 5 Accounts Limit.
15 Accounts = 3 Phones.

If Automate with Jarvee, Not more than 2 or 3 Per 1 IP.
