What is the expected decline in mobile service revenue for the whole year 2020, and what is the expected growth trajectory for the next year
ething going forward, we would like to see it will continue to increase, OK? So that you know. Probably this quarter, we have a small hiccup, but hopefully, we're really expecting though in the future, we have some growth in second quarter after.

So I just have one question on 5G pricing. So it seems, currently, all big three operators are offering early bird 5G plans at around 13 99, but there are some smaller operators offering much lower prices. So can we ask Chunghwa's strategy on the official 5G pricing? Or do we see any pressure to actually lower the price from the early bird pricing level here?
Fu-Fu Shen -- Assistant Vice President & Director of Investor Relation.
I think we are stick within our 13 99, this kind of strategy. You see, for example, like we recently, when we launched Samsung S20, we actually included this kind of in the contract for customers subscribing with 13 99, if you can sign with us with the option with the 5G plans. But out 90% of our customers actually signed with 5G plans, which means, once when we launched 5G service, those customer can automatically become our 5G migrate to 5G. So customers see kind of interesting in 5G service. So we believe this is still a good strategy. We will stay with this kind of things. So this is a 5G handset. So later on, if we have a good 5G handset, probably we will continue this kind of strategy. We will look into that. Actually, I would like to add on something. Now only the 13 99, I think for 5G, not only for the speed, for the data usage, we really would like to see some innovative applications to be included for use in new experience when they migrate to 5G service. Thank you.

I think last time, Chunghwa mentioned that correct me if I'm wrong. You mentioned that for the full year 2020, you still expect decline in mobile service revenue as we have. But now as we have seen some 5G early birds offering in the market, if we look at the initial adoption pace and perhaps client feedback, do you still expect the service revenue to decline for this year? Or you can go back to growth trajectory from this year on?
Fu-Fu Shen -- Assistant Vice President & Director of Investor Relation.
We still expect the mobile service revenue in 2020 is a declining trend since the like we mentioned earlier, the subscription for 5G, in the first stage, still very limited, OK? So for especially for this year. So I think the early burden is this is just a trial, but we would like to maintain this kind of a high end retained our high-end customers and try to maintain this kind of experience, experience, try to give this kind of experience. So for this year, for the whole year, declining trend like this. Yes. So the like we mentioned that next year, probably, hopefully, will be the year we expect 5G will have some kind of performance, hopefully. Yes.

Okay. And to follow-up on the realities in your first question. Should we conclude that handset sales itself actually generate negative margins? Or it's just a lower-margin business instead of negative?
Fu-Fu Shen -- Assistant Vice President & Director of Investor Relation.
Margin itself, of course, net handset sales, of course, yes.
Shui-Yi Kuo -- President, Senior EVP of Finance Chief Financial Officer & Director
I answer your question. Because under IFRS 15, the handset sales and our telecom service under together, we should allocate revenue between our handset sales and the streaming service revenue. So the handset sales usually have a negative margin, but it's the number is not very big. And I add one more information about your question number one. I think the 5G will time to educate this market and which we will stimulate our customers to use 5G services. And I think our goal here, we will aim to provide more and more innova
