mbrown572097 Posted July 11, 2023 #1 Share Posted July 11, 2023 Hey guys, It's been a few years since I have cruised, and I will need to be able to communicate with family (back home) while sailing. We will have the limited internet package so I assume that I will be able to email or text while connected. Do you all have any other suggestions or tips that I can try?

phoenix1181 Posted July 11, 2023 #2 Share Posted July 11, 2023 You can text iPhone to iPhone while in airplane mode without using internet minutes. No photos, just text. It worked great this past December while on an LA to Miami cruise. Link to comment Share on other sites More sharing options...
mbrown572097 Posted July 11, 2023 Author #3 Share Posted July 11, 2023 Wow, really. I had no idea. So I could text family, not on ship, without using my wifi time? Link to comment Share on other sites More sharing options...

You can't exactly text, but on some ships you may be able to iMessage (which looks like a text in the iPhone iOS "Message" app, but colored blue and not green) another iPhone when connected to the ships wifi, but not using your internet minutes. That other iPhone could be anywhere, doesn't have to be on the ship. You would not be able to send a message to someone using an android phone. This is how it worked on Royal Carribean for years, but eventually their IT people figured out how to block this "loophole". I guess it still may work on some NCL ships? I don't want to get too technical, but it seems to have something to do with iMessage using the same protocol and TCP/IP ports as iOS notification messages.

This is definitely an IT glitch, not intended design. So you MAY be able to, but don't count on it. The internet plan will allow e-mail and imessaging to other iphones. You won't be able to "text" non-iphones like your normally would. That uses cell service only, not internet. You could use whatsapp or facebook messenger instead. 2 Link to comment Share on other sites More sharing options...
phoenix1181 Posted July 11, 2023 #6 Share Posted July 11, 2023 Love the things I can learn here! I was able to send & receive iMessages with no problem throughout my Bliss cruise. Didn't try facebook messenger but I'll give that a shot at the end of the month when I head to Bermuda. Link to comment Share on other sites More sharing options...
Ramblin and Gamblin Posted July 11, 2023 #7 Share Posted July 11, 2023 Just to clarify a few comments: You won't be able to communicate in airplane mode. That disables all data flow to and from the device. Instead, you connect to the ship wifi, but don't activate your internet minutes. When you are connected to the ship wifi, you can use the NCL app, but you are blocked from the internet unless you activate your plan. However, as some have commented, there has historically been a hole in the technology that allows iPhone iMessages (blue boxes). So if both you and the other party use iPhones, you can communicate without using your minutes. If you are an Android user, or the other person is an Android user, then you will have to burn minutes.

js Posted July 12, 2023 #9 Share Posted July 12, 2023 I don't understand any of this but have a question. I have an iphone and my adult kids and mom at home have an iphone. I have the internet minutes that come with our FAS but we really won't be using it and reading this thread that doesn't matter anyway. So, with everyone with an iphone is there an actual way for me to text my mom or adult kids while out at sea or do I need to wait to Bermuda, where my dh just calls Verizon before we leave and does the $10 a day thing for call/text. Thank you very much. Link to comment Share on other sites More sharing options...
Maleficent's Dad Posted July 12, 2023 #10 Share Posted July 12, 2023 You can use the ship’s free Wi-Fi - meaning you don’t log in - and iPhone to iPhone works great. At least it did for us on the Joy last week. Same as if texting from home. No pics or vids though. 2 Link to comment Share on other sites More sharing options...
Ramblin and Gamblin Posted July 12, 2023 #11 Share Posted July 12, 2023 When texting with an iPhone, look at the color of the text bubble after you hit send. If the bubble is blue, your text was delivered via iMessage, which slips through without using your minutes. If it is green, then it probably won't slip through.

omahabob Posted July 13, 2023 #13 Share Posted July 13, 2023 (edited) As a point of clarification, you can text from any phone to any phone. You can even text to and from non-phone devices using a gateway, but that's more complicated. Texting between phones isn't iPhone specific. But unless you have some special way around using internet minutes like the above mentioned method (I have no idea if that workaround method actually works because I don't have an iPhone), your messages will go out as SMS over your cell service. Using SMS over your cell service will count against your total minutes, but SMS messaging uses FAR less bandwidth and time than a phone call does, so you're still better off. And yes, you can even send pictures over text using MMS sometimes, but that will definitely use more minutes.

MMS are often separate higher charges. most likely won't be using cell/mobile data as that is also chargeable for most on ship cells. The messaging leakage will most probably be through the wifi. iMessage uses push technology. Push messages(notifications) leak though the wifi on most(all?) devices.

In that case you can also make/receive voice calls (but as you pointed out, that would take longer and use up more of your internet minutes) Link to comment Share on other sites More sharing options...
omahabob Posted July 14, 2023 #19 Share Posted July 14, 2023 Fortunately I had the unlimited plan, so minutes weren't a concern. The wife always insists on unlimited so she can watch the cats on our webcams. I should also caution folks to put their phones in airplane mode when not in port. If your phone automatically switches over to an 'at sea' provider when not in airplane mode, the charges can get very high. Those costs per text definitely kick in there. And if you take your phone out of airplane mode while in port, make sure you cell plan covers you in that location, especially other countries. If it doesn't, those charges can go astronomical too. Older Verizon phones are especially susceptible to this since they use CDMA only, and that isn't directly compatible with many overseas systems. Confirm with your cell provider prior to travel.

omahabob Posted July 14, 2023 #23 Share Posted July 14, 2023 (edited) Very few wireless carriers don't support wifi calling these days. All the major carriers do as far as i know. Wifi calls can be blocked at the port level on local networks, but that would require blocking some common UDP and TCP ports that could also interfere with stuff like Whatsapp and other messaging apps, and possibly lots of other stuff.. I used to do that for a living. Blocking ports is a tricky business, and often comes with unintended consequences. It was a fairly common occurrence to block things you had no intention of blocking. For instance, they all use TCP pot 443. But if you block that, your systems will have major difficulty, because port 443 is used by a ton of stuff. So yes, it's possible they could block it, but not likely. Verizon, T Mobile, Sprint and AT&T support wifi calling, to name just a few, and any phone made since 2018 is most likely able to use it.
