Is it worth investing in an online course for mobiles and tablets?
I've been considering investing in an online course to repair mobile phones and tablets, as it's inconvenient for me to attend a class due to commitments, and of course of the expense of attending a class. I would like to add a mobile phone, tablet and console repair business to my computer repair business I am currently running from home.
Will it be worth investing in a course, or will I be better off with the repair guides on here? Also, on the courses I have found they includes a bundle of unlocking software, is there anything on here that can provide that kind of information?
Is this a good question?
