I wonder if anyone has insight into this one.

I have verizon and tried out sprint for a bit last month. With verizon I am able to text friends in Canada and we both receive the messages instantly with no problems. When I was using sprint, my friend told me that the messages were coming in, but in block form like 160 characters and then another 160 characters. The messages were broken up and also coming in 1 minute, sometimes 5 minute intervals, so and not in order. So it was hard for the recipient to tell the order that the message was supposed to be in.

On my end, I was getting the messages in minute intervals and sometimes a few hours later. Messages coming locally had no issues, and I am in an upgraded area as well, so this does not seem like an issue that playing the waiting game will fix. Why is their such a difference in the way verizon processes international text versus Sprint?

Do not send SMS greater than 160 characters. Otherwise, you are ironically misusing Short Message Service.

True...Messages sent within the US from Verizon to Verizon will come in as one unbroken message. From Verizon to other carriers, its broken up but sent right away so the messages are put in order. Also, from Verizon to Canada its one long message.

From Sprint to Canada they were broken up and out of order and delayed to many minutes apart.

Not necessarily.  The order in which SMS are sent does not dictate the order in which they are received.

 

As I often say, if you need greater than 160 characters, send separate SMS yourself.  Or use a more appropriate medium, such as e-mail or chat.  Remember, it is called Short Message Service for a reason.

Why are you paying for international text when you can use an app like group me. All my friends use it, we have a chat where we all shoot the shit and make fun of each other.

Hangouts works good for this too as android users already have it.

The phone in question is a basic phone, so no apps :)

If it was a smartphone then  whatsapp is what I would use. I don't want to be like a troll, but my questions was skimmed over. The main point was not the out of orderness, but rather the time delay of minutes to hours, vs the seconds it took on verizon.

Here's the issue. No one can really respond. I have had messages truncated before on all carriers. I've also had messages come out of order before on all carriers. We don't all experience the problem you mention you're having on Sprint. So, really, we cannot help you. It is a common and not unique problem to only the Sprint network.

The Short Message Service (SMS) is defined to send a single short message in a single packet.  Coding the characters in 7 bits rather than 8 allows the message to contain 160 characters in a 128 byte packet payload.

 

The SMS packets are not sequenced.  The protocol definition does not require packets be delivered in the same sequence as the messages were sent. If you are familiar with TCP/IP you should think of SMS packets as equilavent to UDP packets, without the ordering guarantee required by TCP.

 

I can readily imagine that given an unordered collection of packets addressed to the same destination the various servers process each packet on any of several threads. Thread scheduling leads to the possibility that the packets, which you think of as sequenced, are processed out of sequence. The more servers a collection of messages passes through the more likely the sequence gets scrambled. Server load is probably the largest variable that results in delivery delays.

 

SMS, like UDP, is a "best effort" service.  You will find no carrier offers even Fortune 50 corporations a delivery time guarantee, or even a guarantee that a message will ever be delivered.  I know of multiple companies using SMS for process control problem alerts ("tank 5 is about to overflow") that want to switch to a different technology because of poor SMS performance where both sender and receiver are in the same state and on the same carrier.

 

Most of the time a collection of related SMS messages happens to arrive both promptly and in the same sequence as they were sent.  However, you cannot assume that the behavior you usually experience is defined as the correct behavior.

      In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). They do have a reserve level. Nationwide 800Mhz is seen as great for new technologies which I presume is IOT or 5g slices.  T-Mobile did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, FWA Mobile in RVs in Walmart parking lots working where mobile phones need all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71, 90% 5g.  93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77 also with its shorter range.

      The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.

      "The company’s unique multi-layer approach to 5G, with dedicated standalone 5G deployed nationwide across 600MHz, 1.9GHz, and 2.5GHz delivers customers a consistently strong experience, with 85% of 5G traffic on sites with all three spectrum bands deployed." Meanwhile they are very close to a construction deadline June 1 for 850Mhz of mmWave in most of Ohio covering 27500-28350Mhz expiring 6/8/2028. No reported sightings.  Buildout notice issue sent by FCC in March 5, 2024 https://wireless2.fcc.gov/UlsApp/letterPdf/LetterPdfController?licId=4019733&letterVersionId=178&autoLetterId=13060705&letterCode=CR&radioServiceCode=UU&op=LetterPdf&licSide=Y&archive=null&letterTo=L  No specific permits seen in a quick check of Columbus. They also have an additional 200Mhz covering at 24350-25450 Mhz and 24950-25050Mhz with no buildout date expiring 12/11/2029.

      T-Mobile Delivers Industry-Leading Customer, Service Revenue and Profitability Growth in Q1 2024, and Raises 2024 Guidance https://www.t-mobile.com/news/business/t-mobile-q1-2024-earnings — — — — — I find it funny that when they talk about their spectrum layers they're saying n71, n25, and n41. They're completely avoiding talking about mmWave.
