hello first of all I would like to introduce, my name is Dimas Putra Pratama. I come from Indonesia.
I was given this account by a close friend of mine.
strangely I have known BTC for a long time in 2015, even I bought about 19 BTC at a price of $210 with a capital of around $4000, but I only found out about this forum in 2021 and was also told by my friend.
so, i have about 19 BTC and i keep it in blockchain.com mobile wallet. bad thing happened to me that my phone was stolen by someone in 2016, even i feel frustrated after seeing current BTC price

. At that time I also registered using the cellphone number +6287**** , made a 4 pin code and the number was saved on the cellphone, I couldn't do much to try to access it because all the data was stored on the cellphone,on the one hand I still have a copy (Prahse Secret Privatkey Recovery) but I'm missing the (Prahse Secret Privatkey Recovery) at paragraph 12

I want to ask for help from the community here to help me, is there any possibility to get BTC back? if anyone can do it then i don't mind giving 3 BTC bonus.
You may contact your network provider to change your mobile number into your old number. You're lucky if they will allow you to change it. Here in my country, if you buy a new sim card and you still want to use your old number, you may call your network provider to change your new sim number to your old one. They actually allow that. My friend's dad did that coz his phone was stolen also. Just try it.
