My 2 cents is that, even being in tech and having a similar background, I don't understand your "resume" as posted here. You jump between stating high-level, vague qualifications (General IT support, capable with linux, various other skills) to very specific qualifications that I frankly don't understand in the slightest (level 3 mobile repair engineer, i have my CompTIA A+, including CCTV, data recovery and destruction). If the cover letters and/or resumes you send out look like this, the people receiving them likely don't understand either. My honest first reaction is that you don't actually understand what you're writing, simply because of how it's been stated. I recommend writing 1-2 sentences that clearly state your value and then organizing your application to clearly support the image you want to convey - ideally demonstrating mastery over your key skills (described so a layman would understand them) through concrete accomplishments (best) or descriptions of courses you've passed (not ideal). Good luck! Keep in mind that I'm just a startup Software Engineer who started in tech support (business-to-business) for a mobile tech company; it sounds like I'm in a very different industry, so take my advice with a grain of salt.
