Hi guys,

Just bought myself a Huawei P10 VTR-L09 phone.
When I check for the specs online I see that there is a VTR-L09 dual sim as well.
On my phone I got the same sim adapter in combination with a micro sd. (its the same as the dualsim adapter)
When I put my simcard in (what should be) sim 2 it doesn't work.
Is this just a software issue, or is my phone missing hardware as well?

Cheers!

Not sure what you mean. Are you saying there is a way to have 2 SIM cards active and still have microSD storage?

remove the plastic cover from the sim and shave the microsd thinner, glue them together, it will fit into the slot. or a adapter, all shown below.

Wow that's pretty cool. Where do you get those adapters? There's like no extra space in that slot, how does that ribbon cable fit anywhere? Do you have more detailed instructions anywhere? I've never tried to dissect a SIM card before.

Would be nice to do it without gluing, so I can still swap SIM cards if I need to.

once modifying the sim and sd card, there is no going back, but it will work with most hybrid slots, except xperia phones. The adapter will bend and locate at the back of the phone.

Ah I see now. Seems a bit clumsy, having to tape the adapter to the back of the phone. Also these SIMcard trays are quite tight when fully inserted into the phone. That ribbon cable is really thin enough to work and not break?

Might try this out later with my P9-Lite before deciding to rebrand my P10.

Thanks, for this! Both my sims are working now. But the phone only booted after unlocking the bootloader again. Is that supposed to be the case? Or did I do something wrong? Sorry for the noob question, but I am new to Huawei.

Edit: nevermind, I did the update step and I am all fine now. Dual sim and locked bl. Learned a lot about Huawei phones in the meantime. Thanks again.
