My print shop is saying that the image is not clear enough.
Printers require at least 300 pixels per inch (which translates roughly 1:1 with dots per inch) or they will lodge this complaint.
I remember seeing something about how you could re-create an image by making programmatically making a mathematical "guess" about what the pixels would be if there were more of them.  If this kind of thing existed, it would be wonderful.
Programs like Corel Photo-Paint and Adobe Photoshop have had the ability to "interpolate" missing pixels for years, but you have to do the math.

The image you are trying to enlarge is 781 pixels wide spread out over 10.847 inches (72 pixels per inch). Printing requires 300 pixels per inch minimum. So if you use Photoshop to add pixels in-between existing ones the image now has 3,254 pixels in the same 10.847 inch space. Photoshop has had to mathematically guess at (interpolate) the color values of 2,473 pixels for every pixel in the image's height. In other words, for every one original pixel, Photoshop is adding 3.2 interpolated pixels. The image is now something like 75% computer interpolated. Now you want to make it 90 inches wide. 90 X 300 pixels per inch is 27,000 pixels. So for every original pixel, Photoshop has to interpolate 34.6 pixels to make it that wide. That's less than 3% original and 97% of the image is computer wizardry. Remember that a computer doesn't know if it's a face or a basket of fruit. It just sees color values in individual pixels. With that much enlargement it's going to look like garbage, guaranteed! So much so that you will need to stand back ten feet just to discern the subject matter of the image. It will look like an impressionist painting with a chimp holding the brush.

If it were possible to make a high quality, billboard size image from a postage stamp size image then there would be little need for photographers an digital illustrators (except to create the postage stamps).

Digital images follow the rules of life. You can't get something for nothing. The small version has a limited number of pixels that define the image we perceive. Making it larger would require an exponentially greater number of pixels that do not exist. Image editing programs can "interpolate" when increasing the resolution and/or dimensions of an image. Interpolate means the program makes an educated guess at what color the new pixels might be based on the original pixels near by. But it's very limited and the resulting larger image is often of poor quality.

What you need is a digital illustrator to reproduce a larger version of the original image.

Also, you can't just take images off the internet and use them for your own purposes without the permission of the copyright owner.

If you had a tiny thumbnail that you needed large,  is this case you'd end up rebuilding much of it.  Like Tom Beck pointed out,  You can't make a low quality image into a high quality with some sort of easy button or conversion.  

You would need to rebuild it.   So find a font that matches up, recreate the gradient,  basically rebuild what's there but at the bigger size.    

Here's an example i quickly threw together in Photoshop.

And absolutely make sure you have legal rights to use whatever image like strung pointed out.

ok, that would be great on a white background.  I'm looking for a publisher file ideally.

I'm obviously no graphic artist or this would be easy.

If you want this in Publisher,  Create a white project at your dimensions, toss in the text and add a broken phone graphic.

Definitely an improvement.  Still working through all the issues but we should have the right size on the canvas anyway.

I don't use a newer version of Publisher.   I tried opening it in Draw (which handles .pub files) and found that i couldn't set the text big enough for your project.    So i went back into Photoshop and exported out the text and attached here.    I created a black version of the text (because white text on white background might not work out).

Can you send the editable source?

Sure, i would have done that initially, but it's not a .pub

The .psd is 57mb so i had to zip it to compress it.

My print shop is saying that the image is not clear enough.  I don't mind buying a vector quality file of that image.

Can you provide the best version of the phone itself that you have?

I really appreciate your help!
