Not OP, but going through the same thing right now. Just activated my PagePlus SIM, and the results are not good. I activated the SIM using my iPhone's IMEI and immediately noticed the download speeds are significantly slower. Seems like a straight up throttle to me. Upload is actually fairly decent.
However, after activating and running some speed tests on my phone, I put the SIM into my router and it wouldn't even connect at all. Seems like PagePlus/Tracfone isn't allowing any network access to my Sierra EM7565. Restarted and retried a few times to be sure before putting the old SIM back in, which worked right away.
To recap my results so far:
Current VZW Plan**: 30MB download, 10-15 upload, overall very fast and 750GB soft cap. Speeds are the same on iPhone and EM7565.
VZW Prepaid: Similar to above VZW but only when used in a phone. When I insert SIM to the EM7565, speeds dropped to 1-3MB. Hardly usable.
PagePlus: Similar 1-3MB speeds as VZW Prepaid, but could not connect the EM7565 at all. Unusable for me.
** Current VZW plan is from a mystery eBay reseller, and is going to be terminated any day now... It is supposedly post-paid but I'm not sure. The reseller must have went under, so I need a replacement.
Next steps... Going to try and get a refund from PagePage (yeah, right) since I was stupidly optimistic and got the $55 plan upfront. If anyone else wants to try, I would strongly suggest the $12 plan to see if it works for you. 500MB of data should be sufficient for testing.
I am tempted to take my Current VZW SIM into a store and see if they can tell me what type of plan it even is, and if there is anything similar I can pay. I'm willing to pay more just to keep the good service I already have, since I really have no other internet options here besides satellite.
Beyond that, I may have to try a T-Mobile or AT&T MVNO. Coverage on those networks isn't nearly as good as VZW, but I can get one or two bars on my cell phone depending on my location in the house. Might be able to improve with better antennas. Curious to hear from anyone else using PagePlus though..
