Switching from Samsung to iPhone 3gs

[Kikanada]

Hi, my Samsung died on me and I was given a working, unlocked iPhone 3 gs. I'd used it with various providers while travelling in Europe and South America and it worked just fine. But I get a "No Service" notice from Public. The phone returns my IMEI number and shows my PM phone number, so it is reading the SIM card, but not connecting to the network. I tried changing cellular settings but still no go. Any idea what I can do tto make it work? Thank you!

@makkahn28 I wasn't aware of that. Is it a PM rule? Because it worked with many other providers.

@Luddite I checked that thread before starting this one.

I honestly could live without a cell phone but the world won't let me 🙂

Don't mind m28 as you can get data to work on i3gs! Just requires using an APN editing website. The only caveat is that it will make  MMS unusable.

@DK, I remember reading that if iPhone is not using latest is or firmware thing, data won't function, as I remember the multiple posts from ages past on that. Also, iPhone 3 and 4 to a degree are kinda ol and not too much support as opposed to iPhone 5 and now 6

You could try installing the applicable APN settings from unlockit.co.nz with safari on your iphone viaa wifi hotspot or other wifi connection. 

I just switched my iphone 5s runninng IOS 7 and could not manually enter proper network settings to get public mobile network to work.  I had to connect to a wifi, then visit unlockit.co.nz to install the APN provisions for my phone.  It's free btw.

I think the maximum supported ios for the 3gs is ios 6.16

@DanZap while it's nice of you to weigh in with some helpful suggestions here, please note that you've replied to a thread that's been dormant for just over 3 years, last active in Dec 2015.  I don't think anyone on this thread is still waiting for help, I'm pretty sure they've got it sorted out by now, or moved on to other things.
