Learn Step By Step How To Fix Your Own Mobile Phones!

It is an unavoidable fact that smartphones can, and do, break. When they do, people want to get them repaired, but often the only option they have is to take their device back to wherever they purchased it from and have the merchant return it to the manufacturer.

This process of sending it away, having it repaired, and sending it back can take days, or sometimes weeks if the fault is serious, and this can be frustrating and inconvenient for the owner. Being able to repair smartphones for people in your local area could give you a great opportunity to start your own business, or add a repair service to your existing business if you already deal in electronics or phones.

Trends and Facts About Smartphone & Laptop Repair Business

1. Nearly 52% of the World’s population has Internet access – that’s just under 4 BILLION people. Those numbers are heavily influenced by North America and Europe where Internet penetration is over 80% for each continent.
2. Smartphone & Laptop repair is a major segment of the industry. IBISWorld estimates the yearly revenue of the cell phone repair industry at $4 billion, with an annual growth rate of 3%.
3. SquareTrade, a company that insures smartphones, reports “a cellphone in the U.S. breaks every two seconds.” Fragile LCD assembly, short battery life and other breakable parts also contribute to a stable market for smartphone repair shops. Tablet repair is also quickly gaining market share.

Marketing Strategy To Drive Instant Traffic For Your Business

There are over 5 billion cell phone users worldwide since 2010 and this number is growing.The iPhone 4 sells in stores for $199 and $500+ on eBay - can you answer why? Businesses are popping up everywhere advertising to buy your old, seemingly obsolete cell phones. There's a huge unsaturated market that you're unaware of - and it's right under your nose!


No start-up costs. No storefront. no previous knowledge.
Just 30 Minutes A Day = More Money Than You're Thinking


Remember, this does not have to do with mobile marketing or cell phone contracts. This entrepreneurial business model I've created has brought me success for nearly three years. There are NO start-up costs and no previous knowledge is necessary.


What's There To Learn To Begin Making Money, You Ask?Where to buy and sell cell phones, how to maximize profits, the value of new, used, and broken cell phones


How to assess condition and functionality, benefit from networking, and make cost-effective trades.How much to pay for cell phones in brand new, used, completely shattered and unusable conditions.

You can't get this training & information anywhere else!


This is the first ever home-study course which teaches you how to turn a broken Smartphone into a perfect one, and how to make a lucrative income from this RARE skill!

Average Profit for each iPhone Repair is about $100. Most take less than an hour once you've mastered the iPhone Course. One person can easily do 2-3 of these per day while still working on other things.

From repairs alone, it's easy for a one-man operation to be producing a $1500 per week income. That averages out at just under $80,000 per year.
With refurbishment, we'll teach you how to sell broken phones at 100% more than the price you paid. You'll make an average profit of $120 on each iPhone you refurb. Higher, once you use our methods for sourcing parts cheaply.

From refurbishment, working solo you can expect to do 2-3 a day, this will allow you to make a profit from $62,000 - $100,000 every year!

The iPhone Course teaches you to easily scale up your refurb business, and once you start doing that and training employees with this course, the sky is the limit. The market for 2nd hand smartphones is at the beginning of a huge growth curve, your potential profits are only limited by the size of your ambition.

Once you combine the 2 Business Models we teach you, a six-figure income isn't a dream, it's an expected reality.
