i bought a Us Cellular phone off ebay and since it has a sim card slot, i assumed it would work with my gsm sim card. it didnt. my question is that is it possible to flash it from being cdma to work with a gsm sim.
Hi, thank you for using XDA Assist. Generally it is not possible. Whether it is cdma or gsm is hardware dependent.
hi guys
i got this phone ( galaxy core prime - s820L ) and tried to use it with gsm card
but there is no network shown !!
when i checked the network mode it shows just LTE / CDMA and CDMA
is there any way to make it work with gsm networks ??
please guide me
thanx in advance
While the Samsung Galaxy Core Prime does have a SIM card slot, it is a CDMA phone. Switching the SIM for a GSM card will not do anything. I have had two phones that required SIM cards, that are CDMA. My other was a ZTE Warp 4g. While there are ways to transfer to other CDMA networks, swapping the SIM will do nothing for you.
Hey all,
I received this beautiful samsung flip phone designed inspired from yesteryear as a gift from a good mate in China:
http://www.samsung.com/cn/smartphones/samsung-w2017/SM-W2017ZKYCTC/ [use Google Translate - see specifications more for supported GSM bands (a lot of them are AU compatible) but then goes to say phone only works in China, Macao, HK and Taiwan!]
I'm in Australia but I'm finding that out of the two SIM CARD slots. Slot 1 (4G LTE) does not work and a message pops up saying 'It's detected that your inserted card doesn't match the terminal. Please replace it with a China Telecom 4G user card in time'. Slot 2 works fine (but only 2G service!!) which is pretty useless.
Any chance any of you can point me to a solution? My friend tells me the store never provided any prior notice that the phone was locked to the China Telecom telco, simple the GSM frequency bands. Are there any XDA guru's who can cook an unlocked ROM for this phone as it's only released/sold out of China...
Any help, greatly appreciated - would hate to send this back!!!!
Anybody....? Really lovin' this phone, but would be AWESOME if anyone can help me unlock it's 3G/4G SIM Slot 1! I've been liaising with this sim-unlock.net site, are they trustworthy and can do the job? Clearly told them phone is not asking for any unlock code, just doesn't accept non-China Telecom SIM cards for sim slot 1.

Greetings and welcome to assist. Unfortunately I don't know of anyway to carrier unlock samsung phones without either going to the original carrier or a third party unlocking service. The second sim for 2g is normal in china, they have one sim for calls (2g) and one for data (4g)
Regards

Any third party unlocking service that you know will do the job? I really need to get the 4g slot working to make the phone worhtwhile using!
Hi
I have a brand new Galaxy J3 SM-j330G/DS origin is Malaysia and I connected customer support and they said phones are locked to the country. How do I unlock it so it will work on the network in Nepal or any country?
The message I get is:
Invalid SIM card
Network locked SIM card inserted
However my SIM card woks in my iphone perfectly and Im sure if i put it into any other device it will work.
Ok thanks
Hi there,
I have an Oppo Find X5 Lite which is dual sim. I have two sim cards.
Sim card 1: New Zealand on 2degrees
Sim card 2: Australia on Telstra
I travel regularly between both countries. When I'm on WiFi, both sim cards register as WiFi calling which is great, however when I'm out and about in either country, one of the sim cards is always in roaming.
I'm wondering if it's ever been possible for VoLTE of the overseas SIM card to work over the data of the local SIM card.
It's a feature that Apple has on their iPhones but I can't seem to find much about it for Android.
Hopefully someone has a hack I can use to get this to work.
Thanks all!
