Do They Text? The Fellowship of the Ring + bonus Elrond, Arwen, Galadriel, Eowyn, Eomer, Faramir, and Thranduil.
See Gandalf's on this post about The Hobbit characters.
Aragorn: 90% of the time, he's out of cell service. Also, sometimes he goes camping and accidentally forgets it. You've got a better chance at reaching him through Arwen or her brothers. He will reliably send pictures of animals and plants from his camping trips though.
Boromir: To his dad? Never. To his brother? Several times a day. To his friends? Once a week or two maybe. He texts very well, just not often unless your name starts with Fara- and ends in -mir.
Legolas: Legolas doesn't talk much, but get to texting him and your phone won't stop beeping at you. That elf sees everything, so along with cool forest and river pictures, you'll get random gossip about people he's petty about. He sends a lot of...risqué texts to Gimli too, so don't scroll through his pictures.
Gimli: He really doesn't like texting. The only exceptions he makes are for Legolas, Gandalf, and the other members of The Fellowship. He has not yet figured out how to send pictures despite Legolas showing him half a dozen times.
Frodo: Yes. If he has the time, he'll respond to you in rhyming poetry or prose formats (if he likes you). If h3 d035n7 h311 r35p0nd l1k3 th15 4nd 1t5 up 2 u 2 f1gur3 0u7 wh47 h35 54y1ng. And no, he will not explain. He'll also send random TikToks and Vines when he should be sleeping.
Sam: Yes, and he sends lots of flower emojis with every text, and doesn't care if you call him gay. He's secure in his masculinity and likes flowers, ok? 🌻🏵🌹🌷🌸
Merry: It's pretty normal for him, and he likes to have whole conversations with Frodo in verse and Vine references. He likes to have whole conversations with Pippin in emojis.
Pippin: 👍💗💣👨👩👧👦👨👧👧📳. 😈🧙♂️(Translation: Yes! He loves to blow up people's phones! Especially Gandalf's.) Better learn to speak emoji. He'll spend hours creating giant pictures made out of emojis too. He once recreated the Mona Lisa in emojis while drunk and no one has ever let him live it down or figured out how he did it.
Elrond: He's in 2 of Gandalf's group chats and doesn't regret it. He pretends to be all proper, but he wants to know all the gossip. He transitioned from sending Aragorn helpful little reminders to angry emojis once he started dating Arwen. Secretly, though, he thinks Aragorn is better than 90% of the guys she could be dating.
Arwen: Yes. Tons of selfies too! Somehow, autocorrect has never changed a single word she's texted. She, Eowyn, Eomer, and Aragorn have a group chat titled horses where they just send each other pictures of horses (and occasionally Eomer in a horse mask terrifying his little cousins). Every time Aragorn sends in pics of other animals, they send angry emojis (unless it's a baby animal or dog).
Eowyn: At first, no, but once she got a phone that wasn't a Nokia, yes. Like Aragorn, she can be hard to reach sometimes. She loves to go trail riding and mountain climbing, and mainly sends beautiful landscaped. She thought the group chat would be awkward because of her crush on Aragorn, then she met Faramir and decided she would take that boy on ALL the road trips and get selfies with him on all the famous places. Embarrassingly enough, they didn't realize they were dating until uncle Theoden and her brother Eomer started telling everyone about how nice and polite her boyfriend is.
Eomer: His name keeps autocorrecting to Elmer and he is not happy about it. He's long term military, and sends lots of photos from around the world. He tends to drunk text a lot, and Faramir likes to send him and Eowyn mad libs filled in with his drunken ramblings. He says he hates that... and yet, still texts Faramir every time he drinks and sometimes follows up with him if he doesn't get a Mad Libs after the hangover is gone.
Galadriel: Yes. It's hard to tell when she's texting sometimes. She has all the details on everyone because people tend to forget they've added her to group chats, and she doesn't correct them.
Faramir: Texts his brother every day and his dad never. He was terrified of Eomer when he started dating Eowyn, but Eomer basically said 'new little brother!', and now he's in the group chats. Eomer and Eowyn also text him with alarming frequency that 'hey, I'm at your house, road trip time.' Boromir's not jealous, just super happy his little brother has friends now and goes places instead of staying near their abusive dad all the time.
Thranduil: He has a gossip chat going on with all of his kids, but mainly Legolas since he's the one who goes everywhere most often. He and Gloin mourn about how their sons are dating- not because they're dating men, but because do they really have to date the son of their rival company's CEO? He also drunk texts Galadriel and Elrond a lot, forgets he did it, and gets creeped out by how much they seem to know about him.
