Hey everyone,

I’m looking to add some freedom to my mobile device setup and could use some advice from anyone who might be familiar with what I am trying to do.

I am currently using an iPhone, but I generally prefer using android devices. In the past I have regularly switched back and forth between the platforms but it’s a pain to do and (being based in the U.S.) the turning on and off of iMessage tends to confuse the people I communicate with (and confuse their phones on occasion when it fails to acknowledge my number is no longer registered with iMessage). I also just got a Pebble Time 2 and want to use it with android to get the full experience.

Normally I would just make the switch, but I’m hoping I can decouple my setup a bit and get the “best of both worlds.” Due to a recent BOGO deal at T-Mobile, I have an unused line in my family plan that is free. What I would like to do is keep my main phone number tied to the iPhone I have but have it act as a relay for iMessages, calls, and RCS/SMS/MMS messages to my android device that I would carry with me.

Not only would this make switching devices easier in the future, it would allow me to seamlessly go back and forth between iOS and android with almost no disruption whenever I want to.

Here is a simplified list of requirements/questions I need to solve for this setup:

1. How to make and receive calls from my primary phone number on the secondary line (I assume I can setup some kind of call forwarding but that would only cover the receiving of calls)

2. How to send and receive iMessages from my primary phone number on the secondary line

3. How to send and receive RCS/SMS/MMS messages from my primary phone number on the secondary line

Would love to hear this community’s thoughts and advice!

I need a German phone number, so I need a German SIM.

My preference would be a prepaid year because it’s a bit cheaper. Also, I have a physical sim slot and would rather use a physical sim than an eSIM.

Many apps (Mein O2, MeinMagenta for cell services and most of the local transit apps) are region locked. I can’t currently change my Apple ID to Germany and can’t make a new Apple ID for Germany without a German phone number.

Any hot takes on Telekom, Vodafone, O2, etc. or recommendations on getting a physical SIM card?

Note: The Aldi closest to me only had eSIM today or thought they only had eSIM.

Edit: I actually need a phone number for things, e.g. kita being able to call me if one of my kids get sick at daycare.

Quick background: wife inherited an iPhone 8 plus from a recently deceased relative. Said relative used to have AT&T, wife and I do not. I was hoping to possibly use this phone on an upcoming international trip but it would need to be unlocked from the carrier first so I can put a new sim card in it. (Just to be clear, I don't mean getting into the actual phone, we've already saved the few photos and messages that were on there and reset the phone to factory settings). Tried doing the automated process on the AT&T website and it was denied immediately, no explanation given. Tried calling them and the automated system straight up hangs up on me because I don't have an account with them. So lastly we tried taking it directly to an AT&T store where they directed us to either call the number that keeps hanging up on us, or to "take it to one of those places at the mall that can unlock it for you". Useless.

I've done some research on this and seen various solutions online. Most of those solutions I have already tried (like calling the number or trying the online portal thing) or their situations don't apply to my case (like having purchased a new phone or having an account already with AT&T). One thing I've seen mentioned multiple times that seems to get results is to file a complaint with the FCC, so I went to do that and welp... government is shut down. FCC not accepting any complaints at the moment.

Another thing that I thought of was jailbreaking the phone, but I haven't done that to a phone in many years and am not even sure if that would resolve the issue of it being carrier-locked. But surely if 'those places at the mall' can unlock them without going through AT&T, then I might be able to as well. Hence I came here asking for help.

Anyone have any experience with this sort of thing?

Could someone please recommend a text messaging app for Android that is reasonably secure?

Verizon is discontinuing their native texting (SMS) app. They recommend switching to Google Messages, but I would not like Google to have access to my entire text messaging history. I tried Signal, but my old messages don't transfer over (minor problem), and almost none of my family are willing to switch to Signal (big problem). When I search for advice, I get a bunch of AI slop articles and advertisements. So I figured I might have better luck asking here: Is there any text messaging app for Android that works well and isn't going to hoover up all my data?

I've been a long time Fi user on the Pixel line of phones, so I've always gotten the gold standard of service from Fi. My wife is an adamant iPhone user. We want to port her over to my plan, but I was hoping to get some recent feedback from anyone using a modern iPhone (just bought her a 16) -- All the things I find on Google are months to years old. If this is you, how well do the iPhone features (Visual voicemail, iMessage, RCS, FaceTime, 5G, etc) work for you on Fi?

I am going to be living in France for the next year. I want to keep my US mobile phone number, and I would like it to be somewhat usable while I am out of the country, but I can't find an affordable way do set this up. I am hoping someone here has some more insight for me.

I am going to be buying a French mobile phone plan (most likely through Orange) that will cover my data usage, along with a local number for calls and texts. I already have either whatsapp or imessage set up for calls and texts to/from my family in the US. Ideally, I would like to have my US number on a second sim on my phone. I wouldn't need any roaming data for that sim, just calls and texts, and my actual usage will be very small.

Here are the solutions I have explored:

1. Porting my number to Google Voice. This is probably the best solution, but I would like to avoid google if at all possible. This costs only $20 with no monthly fees. This would require me to use a separate app for this number. If possible, I would like to be able to use the iPhone system apps for calls and texts.

2. Some MVNO with international roaming. So far the best I have seen is Ting mobile. It costs $0.30 per minute calls and $0.12 per outgoing text. This pricing would be perfect for my extremely low usage. However it requires a $10/month pay as you go plan which is more than I want to pay.

3. IoT sims (although I am almost positive this won't work). These appear to be sms and data only, so for my usage they would be sms only. Telnyx is the service I found that actually supports esim (my phone has only esim). I am having trouble with the console, but I am trying to get an esim on my iphone. If this can work, it would be only $2/month plus usage, which would be perfect.

Are there any other possible solutions that I should look into?
