I have T-Mobile OnePlus 7 Pro for almost 14 months ( with a Texas Number), I'm in Canada and I'm always roaming with Telus network. T-Mobile wont unlock my phone for another 10 months.
I have already flashed my OnePlus with International Firmware successfully, I also bought a dual sim card tray to use both Networks (T-Mobile and a local network) at the same time so people don't have to call a long distance to reach me; I can see 2 sim card however the second SIM card is greyed out.
What do I need to do next to reach my goal?

Hello Everyone,
I am facing this weird issue. Mine is a dual sim E8 and I was using Airtel provider on my sim slot 1.
The moment I landed in US and when I powered on the mobile, it was showing no signal . Till this moment I havn't changed or removed any sim card. The settings are still untouched and even the sim tray has not been removed ,airtel sim in slot one and no sim in slot 2. Later I changed the setting to manual mode , I saw a pop up displaying sim card error and "unable to find network, switch to global mode"
Then i moved the Airtel sim to slot 2 with slot one empty. It asked me to select Tmobile or ATT as partner network. I went with Tmobile as roaming partner.
I wanted a dual sim , as I was hoping to use Tmobile/ AT&T sim on slot one and keep Airtel sim on slot 2 when I reach USA.
Later , I brought a Tmobile sim and put it in slot one, same old error pop up, but it worked in slot 2 ( Edge )
I reached HTC chat , its the most horrible experience i have ever had. The moment i tell them my issue, chat window loses connection as if someone has disconnected.
Finally when I did get connect , by checking my IMEI, chat representative told me that slot one wont work for roaming as its CDMA, only slot 2 works for roaming.
I just couldnt understand this, I was using airtel GSM sim in India with 2G internet. how come an unlocked device change to cdma while roaming outside India.
Please let me know how to work on sim slot one issue. I love this mobile a lot , even if i get 2G on slot one , i will be very happy
Mobile is in stock condition purchased 2 months back, I received a factory update to 5.0 through OTA
I bought my phone from India around a year ago. I migrated to USA. Here SIM slot 1 is not working at all. I'm not able to get any network. And on SIM slot 2 I'm not getting any internet connection. I'm using t-mobile as my network operator.
I bought the Google variant and provisioned it on Verizon. I already have an activated prepaid SIM I've used for UK in the past.
Is it as simple as popping out my LTE sim and popping in the GSM one? Will I run into problems coming back to USA? (I will need my phone to be active as soon as I land at home so that I can get transportation to my house.
Location: Japan
Carrier: au KDDI and/or Docomo
Phone: OnePlus 7T Pro McLaren Edition (T-Mobile unlocked)
My phone that I bought through au KDDI broke and I wanted to get a new phone anyway, but I wanted to venture into the world of unlocked phones for the first time. I know there is complications with getting phones that are unlocked and compatible with carriers with regards to CDMA/GSM, frequency bands, etc. When I checked info on frequency bands for the OnePlus 7T Pro McLaren I bought it seemed like it would work but it didn't. Still doesn't work with a new carrier who seemed even more likely to work.
Timeline:
1. Using au KDDI
2. Buy this OnePlus 7T Pro McLaren Edition (T-Mobile unlocked)
3. Put in au KDDI sim card. "Emergency Calls only/No service"
4. Manually make APN settings. Still doesn't work
5. More research looks like au KDDI is maybe CDMA, and that phone only works on GSM. Docomo is GSM and many reports of Docomo being usable with many unlocked phones.
6. Buy this prepaid sim card that apparently uses Docomo's network as a test, per advice of anonymous online user.
7. Put in prepaid sim card; works immediately without any APN shenanigans or anything.
8. Go to Docomo, sign a contract with them and get a sim card.
9. Put in new Docomo sim card, and doesn't work ("Emergency Calls only/no service") regardless of which APN settings I select or make.
I give all the links to the exact products and companies I'm using in case someone can find the compatibility issue. Is there something I can do or do I just give up and return this OnePlus 7T Pro McLaren? I'd like to maintain my contact with both companies and try different unlocked phones until I find a phone/carrier combination that works, but do you think any unlocked phone would work? Am I stuck using the phones they carry? Also why would the prepaid card on Docomo's network work but not their actual sim card?
Bought phone from India, live here in Canada.
Just to confirm for clarity sakes.
Use an Indian Sim card here in Canada, and make a call here to some number for 5 minutes.
Switch sims to Fido (Canadian Network) no issues?
Confirming since this is the first time I have ever read/heard about the above.
Ideally, that should have been done when in India. Try, hopefully it still works
