So I just ended up getting a Saskatchewan plan on my account, with an Alberta number by going to a corporate owned Telus store at Southgate Center in Edmonton Alberta, and even short cutted the process in doing so. It was very easy, and fool proof. It's a bit different than the instructions on this thread, so here's the rundown of what I did.
1. Purchase a Virgin Mobile Sim Card. I purchased it from the Source, but they are available at Staples and Virgin themselves. The Sim cost me $4.99 + GST.
2. Go online to virginmobile.ca and click the link to activate a sim card on a new prepaid account.
3. Follow the instructions online at virgin, and make sure to select a Saskatchewan number (Area code 306). I entered my actual Alberta Address while doing this. You DO NOT need to add any funds to the pre-paid account. It will also ask you to create a 4-6 digit pin, so make sure to remember this too.
4. After activating the virgin mobile pre-paid account, and setting up a Saskatchewan number, call virgin mobile prepaid account services (1-888-999-2321) and ask them to give you the new prepaid account number. This is not the phone number, but rather a 13 digit account number. Write it down, as you will need this later on at the Telus Store. The virgin mobile customer representative did ask me why I needed my account number, and I was honest and said I was porting it out. He then said that was fine and gave me the account number.
5. Go to your local Telus Store in person. I went to a corporate owned location in Edmonton. Not sure about 3rd party dealers. When you are there, tell them you want to switch your number from Virgin prepaid to Telus. Do not tell them it is a Saskatchewan number just yet. Just play dumb when you are discussing what type of plan you would like, and just choose any plan that is available to Alberta. Do not worry, you wont end up with an Alberta plan when this is all over. The Telus associate will sit down with you and start the new account process. When it gets to the point that you are going to get a new number assigned, make sure you tell them you would like to port in your previously created virgin mobile phone number (which is the Saskatchewan number). DO NOT set up the account with a local number, insist on porting in right from the get go. The Telus guy didn't say anything to me about the 306 number, but if they do, just say you have a business in Saskatchewan or that you go to school there or anything really.
6. When you are in the porting area of setting up your account, give the rep the Saskatchewan phone number's account number (that you previously received by calling virgin mobile), along with the 4-6 digit PIN that you created when setting up the virgin account number.
7. The port in process was pretty much instant.
8. After you have transferred the number into your Telus account, the only plans that were available to select were Saskatchewan plans (ie. the cheap ones that you want). The Telus guy can't even select a non-Saskatchewan plan at this point, and didn't seem to care that was all you could pick from. I ended up taking Unlimited Canada/USA calls and texts, plus 15 GB of data for a total of $85/month.
9. After you are done at the TELUS store, go home and create a telus account to manage your new wireless service. After I set up my telus account access, I then went to the section that listed my devices. Underneath your listed device, it should list an option to check on your number transfer status. Click on this, and it will bring you to the classic my account website, which is what you want. When you are in the classic account website, click on the link that says "change phone number".
10. Proceed to port in your local Alberta/ON/BC number from your main carrier you had previously (not the virgin mobile number you used in the previous steps). Port that number over to telus, and it will change your Saskatchewan number to a local number while keeping you on the Saskatchewan plan you selected at the Telus store.
This process I followed had my Alberta number set up with Telus on the same day without having to wait for the first billing date to come and go, since I didn't have to bother with creating an Alberta number, switching it to a Saskatchewan number after the first bill, and then porting back to an Alberta number again. I just started my Telus relationship with a Saskatchewan number from the very beginning. I hope this was of value to someone. Good Luck.
