Service disabled sprint

[X3am]

I bought an g7 on ebay to use on tello a sprint mvno and upon putting in a sprint SIM card I got from sprint for this phone I get service disabled and no bars. I got another sprint sim and Same thing. I tried my wife’s iphone5 verizion SIM card in it and immediately had bars and functioning data but no calls or text. I’ve called sprint and tello and they both say it’s on my end and I believe them. Do I need to flash the modem? Can I do anything or should I return it or will the next one have same problems? Any help greatly appreciated

Does the phone you bought support the correct bands?
What is shown on the box the phone came in?
Ii'm aware that some advertised as "GSM only, no CDMA" but write what is shown directly on the box.

Write that in a reply here but also call sprint DIRECTLY and ask to speak to a HIGH LEVEL tech--not the basic clown monkey, but someone who actually knows what they are talking about.
Give them the bands and modes shown on the white sticker on the box and see if they can make it work.

If you want to change bands, dial *#546368#*710#
Then go to field test and engineering mode and you can change the LTE bands there. Find out which bands are supported.
You can also change the GSM modes but they had better be on the phone to tell you what to set.
After changing any bands, go to network mode and set it to automatic, or phone calls will not connect at all.

Thanks for the reply. So I’m learning more about the phone as I go, there was no phone box, it just came in a simple brown shipping box. So on the phone itself there’s a sticker that says the meid as being a sprint version of the phone but when you check the settings it’s a different unlocked version. So I’m thinking some one rooted/unlocked a sprint version and resold it. Which okay, so now does that mean I can’t get updates? I’ve never rooted a phone so this is new to me. If i switch carriers and get the network working will I still not have the updates I want?

Sorry I cannot help with this as I have no knowledge of these things.
My phone was an official retail box that had the "made in korea" sticker on it, the model number, three barcodes (dual sim) and all of the bands supported.
If yours didnt have this, you probably should just return the phone.
Always make sure you buy NEW, boxed phones and not third party.
