VOIP Tech Chat → [General] use voip on iphone 4s with tablet flex data plan

Hello, I'm new to voip and have been reading through the forums to educate myself before embarking on this journey. I have purchased an OBI 100 and am currently evaluating Anveo and Voip.ms (I know there is quite a debate).

Goal: minimize home and cell phone bills

I'm not interested in SMS as I rarely use it. I chose Anveo over Voip.ms as I read about some recent problems with Voip.ms. My requirements include:
- pass WAF - must be stable and good quality
- low cost
- easy to setup/maintain as I'll be configuring many relatives houses to do the same
- use on my home phone (via OBI) and my cell (bria, others). Ideally i'd like to setup my wife's cell as well, but again it must pass the WAF

Based on my reading thus far, I really can't go wrong with an OBI and either of these providers. My decision will most likely depend on the last point... usage on cell phone and minimizing my cell bills.

My jailbroken locked Bell iPhone 4s doesn't allow me to view/modify APN. I found a site called tweakker.com/iphone that looks promising. I haven't tried it out yet as I don't want to break my phone as I have yet to purchase a tablet data plan/SIM. I'm hoping the experts in this forum can offer suggestions or guidance for me on what process I should follow?

My guess is I should do the following:
1. purchase a micro sim from Bell/Rogers/Telus for their tablet data flex plan
2. insert sim into my iPhone
3. switch WiFi on and navigate to »tweakker.com/iphone
4. Select the carrier chosen above
5. select subscription (Standard or Tethering) - not sure which I should choose... my guess is Standard
6. continue following the prompts from the tweakker tool

I would follow the same process when I go down to the States as well and choose one of their providers.

If there are other options to minimize all my bills while offering stable, high quality service... I'm all ears.

Looking forward to your responses. Thanks in advance.

You need IMEI from an ipad with 3G to activate an account with flexi plan. I did it with rogers. Without the IMEI, you can't activate your SIM. After, you can put your new sim in your iphone and it will work.

About voip and 3-4G, it is not perfect but it is low cost like you want.

VOIP over 3G will not sound good, I tried Verizon and T-Mo. You will be fine over WiFi

I would be cautious about putting your relatives on any VOIP service and I say this as Anveo and CallCentric customer myself. If they have a problem there is too many variables for non-technical person to troubleshoot, especially during an emergency. Plus a lot of people may not appreciate the concept of paying per minute for outgoing calls and 800 calls.
