My iPhone will send iMessage but not regular text messages?

Ok so Yesterday I upgraded to an iPhone 5s from an iPhone 4, It went great until I got home. I could send all the iMessages I wanted but my phone is having trouble sending and receiving regular texts from android or other non iPhone devices. The thing is I also have an airave in my house to boost my signal because the house I live in has thick walls. On my iPhone 4 it worked great with no problems but now its all messed up! I call the support for Sprint (My carrier) and they walked me through some steps that seemed promising such as: Turing off iMessage and SMS on the old iPhone 4 and also on the iPhone 5s then restarting the iPhone 5s and leaving the iPhone 4 off. It did not work, I even changed my iCloud password and factory reset the old phone after deleting the iCloud off of that phone. Nothing is working and I won't be able to talk to some of my friends or family or even my job if this does not get resolved. I don't know what else to do? Should I factory reset my new iPhone 5s and just restore it from iCloud?

Did you enable you data and kept your Wi-Fi on, that happen to me when I didn't pay my phone bill sp when my iphone was off whenever I was around Wi-Fi I can only use internet for I message only I couldn't call out or text

If you can't send and receive SMS

You will need these to send and receive SMS:

An iPhone
A strong cellular network connection through a cellular network provider
A domestic SMS plan from your cellular provider (You might need an international messaging plan to send SMS to an international contact. Contact your carrier for more information)
A roaming SMS plan when you use a cellular provider's network that is different from your billing cellular provider's network (Learn more about roaming and contact your carrier for more information.)

To resolve issues sending and receiving SMS, follow these steps

Go to Settings and turn airplane mode off.
Make sure that you have a cellular network signal in the status bar of your iPhone. Restart your iPhone.
Tap Settings > General > Reset > Reset Network Settings on your iPhone.
Remove your SIM card and insert it again.

If you still can't send or receive SMS, follow these steps

Make sure that the contact who's trying to message you isn't blocked in Settings > Messages > Blocked.
Make sure that you're using the area code with the contact's phone number. When sending messages internationally, you also need to use the contact's international code.
If you're using a "Pay as you go" SMS plan, make sure it has enough available balance. Contact your carrier if you're unsure of your SMS plan or the available balance.
If the issue occurs with a specific contact or contacts, back up or forward important messages and delete your current messaging threads with the contact. Create a new message to the contact and try again.
If the issue occurs with a specific contact or contacts, delete and recreate the contact from the Contacts app. Send a new message to the contact.
Back up and restore your iPhone as new.
If your carrier has recently ported your phone number, the porting process might not be complete. Contact your carrier to confirm that the porting process is complete.
Contact your carrier to confirm that you're provisioned for sending SMS and are in an area with cellular coverage.
Contact your carrier to verify there are no blocks or filters placed on your wireless account preventing you from sending SMS.
