ABSTRACT
Customer’s (use) purchasing decision making have the crucial point of several
marketing decision-makers in all type of businesses. Studies have suggested that
ambiguity still exist in terms of variables capable of enhancing the indirect link
between the promotional mix (PM) and customer’s purchasing (use) decision,
specifically in the cellular communication sectors of most of the developing
countries. This study is an attempt to explore the link between promotional mix
(PM), consumer trust, and customer use decisions in the context of Yemen cellular
communications sector. The hierarchy of effects theory is used as underlying
theory, and quantitative cross-sectional survey method with questionnaire were
used in collecting data. The random sampling method was used in distributing the
questionnaire to 382 respondents. The Partial Least Squares Structural Equation
Modelling (PLS-SEM) was used in analyzing the data. The result shows that
promotional mix and customer trust has significant and positive effect on customer
use decisions, and customer trust mediate the link between promotion mix and
customer use decisions. Finally, the study provided some useful suggestions for
future studies.
Keywords: Consumer trust, promotional mix, customer’s decisions to use, Yemen.
INTRODUCTION
The telecommunication sector has become an area of interest to numerous researchers. This is
because of its features that tends to distinguish it from other kind of sectors of every economy
in the world in terms of high growth rate and rapid technological advancement as well as its
overall contribution to growth of other related industries (Saif et al., 2021). Hence, the
telecommunication sector is said to be amongst the vital infrastructure a country requires for
its overall growth and development. The availability of telecommunication system in a country
helps in attracting several investors, it also helps in enhancing the diversification of
productivity among several industries as well as decrease the cost of transportation by
ensuring easy access to the market (Pradhan et al., 2017). The communication sector is
regarded as one of the most productive sector of the economy of different countries of the world
(Pradhan et al., 2017). In most recent times, developing countries have acknowledged

significant transformation in the telecommunication sector considering its influence on their
economies (Qasem et al., 2022; Saif et al., 2021).
Thus, the development of technologies as well as mobile phones has stretched the history of
advancement and innovation picked up considering the dynamic changes in consumers’ needs
and their service preferences. Part of these advancements, cellular phone devices have gained
the wildest household adoption rate amongst other technologies in the global modern history
(Comer & Wikle, 2008). Nowadays, cellular phones have become integral aspect of human day- to-day life as well as personal communication across the world. In the present highly
competitive cellular phone market, and its continuous adoption by individuals across the world,
service providers are constantly striving to find more competitive edge and other
differentiating elements towards persuading consumers to choose their services instead of
their competitors. Although, several economies, especially in developing and emerging
economies, still distrust the benefits of competition regarding cellular services. Thus,
international experience suggests that competition in digital technology provides substantial
benefits to customers by creating prevailing incentives to the service providers to lower the
prices and introduce new services as well as enhance productivity (Carlo et al., 2021).
In Yemen, the telecommunication sector is one of the major sectors that has been contributing
greatly to the country’s economic development (Al-Bashiri, 2021; Saif et al., 2021). The
increasing rate in the use of cellular phones can be related to widespread and availability of
telecommunication services in the country. In consideration of the significance of the
telecommunication sector, several companies such as MTN, Yemen Mobile, and Saba-Phone
have entered the cellular communications market in Yemen with approximately 18,708,333
subscribers amongst the entire cellular companies (Sana’a, 2021).
Hence, these telecommunication companies have been engaged in fierce competition amongst
themselves for the purpose of obtaining the largest amount of market share in the sector. Thus,
several studies have shown concern on the need to focus on the decision to buy/use by the
customers and the factors affecting the companies seeking to obtain the highest market share
(Abdelhady et al., 2019; Ahakwa et al., 2021). Thus, considering customer’s limited knowledge,
the buyer may be constrained rationality while trying to choose appropriate rating criterion
(Rafdinal & Amalia, 2019). Customers tend to purchase products with higher prices due to the
believe that the products are highly qualitative (Qasem et al., 2022). Consequently, companies
must develop a certain strategy so as to influence this phase towards increasing the number of
purchasing decisions made by customers (Rafdinal & Amalia, 2019; Yacub, 2022). Based on this,
previous studies have emphasized on the importance of promotional mix in providing a mixture
of vital information to the customers regarding products and other services available in the
market which tends to offer them with different alternative choices towards making intelligent
decision on particular products (Abdelhady et al., 2019; Vincencia & Christiani, 2021; Yeboah,
2021). In addition, studies have suggested that customers trust is capable of boosting the
indirect effect of promotional mix on customer’s decision to use cooperate services (Abimbola
et al., 2020; Rafdinal & Amalia, 2019). However, the main idea of this study is to conduct an
empirical exploration of the mediating influence of customer trust in the relationship between
promotional mix and customer’s decision to use cellular phone services.

Problem Statement
The telecommunication business has become highly competitive due to the technological
advancement that took place in most of the developing countries and Yemen in particular. This
advancement has reduced the rate at which customers changes their service providers from
one telecommunication product to another. However, customer’s buying decisions solely
depends on the best service and benefit provider amongst the telecommunication products
(Abimbola et al., 2020; Qasem et al., 2022). It has been revealed that the market share of the
telecommunication companies has been affected due to the fierce competition amongst the
companies in Yemen. For instance, Yemen mobile gained largest market share with
approximately 40 percent, Saba-Phone 28 percent, MTN 27 percent, and company ‘Y’ 5 percent.
This indicates that the Yemeni consumers are rapidly moving from one service provider to
another with fluctuating subscribers between 2011 to 2019, suggesting that there is serious
problem regarding customer trust in the cellular communication service providers amongst the
four companies in Yemen. This have reflected in customers’ decisions to use cellular services
provided by the four companies operating in Yemen. Studies have indicated that for a company
to gain relevance and most preferred by the consumers as well as compete in a larger market
share, it has focus much on promotional activities geared towards ensuring a greater
competitive advantage (Abimbola et al., 2020; Al-sharafi et al., 2018; Qasem et al., 2022). Hence,
promotional activities such as; sales promotion, advertising, personal selling, public relations
and publicity are all considered as marketing efforts used in presenting company’s products,
its features, as well as what distinguish it from other products (Alananzeh et al., 2018; Clow &
Donald, 2017).
Inspite the importance of these activities (promotional mix) towards customer’s purchasing
decision, there is a paucity of studies investigating the link between the elements of
promotional mix as a group and customer’s decision to use cellular communication services in
Yemen (Qasem et al., 2022). Based on this, several studies has recommended for the need to
investigate the mediating construct such as customer trust which is capable of describing the
link between promotional mix and customer’ purchasing decision (Abimbola et al., 2020;
Rafdinal & Amalia, 2019). Hence, this study is one that seek to examine the mediating role of
customer trust in the link between promotional mix and customer’s decision to use cellular
communication services in Yemen. Thus, the paper suggest that ensuring customer’s trust in
the telecommunication sector in most of the developing countries, especially in Yemen through
promotional mix (sales promotion, advertising, personal selling, public relations and publicity)
may have significant effect on customer’s decision to use cellular communication services in
Yemen as well as the entire system.
Research Objectives
The current study aimed at exploring the mediating influence of consumer’s trust in the link
between promotional-mix elements (advertising, personal selling, sales promotion, publicity,
public relations) and customer’s decision to use cellular phones in Yemen. The main research
objectives are;
a. To examine the link between promotional-mix elements and customer’s decision to use
cellular phones in Yemen.

c. To investigate the effect of consumer trust on the customer's decisions to use cellular
communication service in Yemen.
d. To examine the mediating influence of consumer’s trust in the link between

Underlying Theory
In quantitative studies, theories are mostly used in order to assist the researcher towards
answering the research questions (Cresswell, 2014). The main theory used for the purpose of
this study is the hierarchy of effects theory.
The Hierarchy of Effects Theory
The current study is based on hierarchy of effects theory (AIDA model). The theory was
propounded by Lavidge & Steiner, (1961). Thus, it is a prominent theory in the field of
marketing communication framework (Nzioka & Waithaka, 2021; Páramo et al., 2021).
According to the theory, there are three primary channels through which a company's use of
promotional mix tools might affect customers' buying decisions. These are the cognitive,
emotional, and conative or behavioral processes (Nzioka & Waithaka, 2021; Páramo et al.,
2021). The first channel is the (cognitive element) which indicates that customers have
received messages and are fully aware of the messages. The second channel is the (effective
element), which tends to demonstrate the generation of a particular attitude as well as reaction
to the promotional messages (Nzioka & Waithaka, 2021; Páramo et al., 2021). The third channel
is the (conative or behavioral component), which stands as the act of actual purchasing of the
promoted product (Páramo et al., 2021; Tafa, 2018). The theory demonstrate the development
from consumer’s initial state of ignorance to their subsequent awareness of promotional
messages and behaviors as well as their subsequent reactions. The theory has been identified
as a powerful foundation for understanding the link between promotional-mix and consumer’s
purchasing decisions. Interestingly, several studies such as Nzioka & Waithaka, (2021), and
Páramo et al., (2021) have applied the hierarchy of effect theory in their studies and achieved
suitable result. Hence, the current study applied this theory in explaining the complex
relationship between the study constructs.
LITERATURE REVIEW
Consumer Purchasing Decision
Consumer purchasing decision is seen as an integrated procedure which mostly begins with
thinking that subsequently leads to consumer’s feeling of need of a particular product, then
research, determining the need, searching for options as well as comparing amongst such
options, then making choice of a particular product that tend to satisfy the consumer’s need
(Ahakwa et al., 2021; Faulds et al., 2018; Yeboah, 2021). In this study, consumer purchasing
decision is used a dependent variable.
Promotion Mix
Promotion mix is seen as the set of ingredients which mostly react and integrate together for
the purpose of attaining company’s promotional goals on the context of philosophy of
marketing principals (Abdelhady et al., 2019; Alananzeh et al., 2018; Kotler et al., 2017). Thus,
promotion-mix consist of a group of elements which includes; (a) advertising, which is
described as non-personal marketing communication regarding a company, product, service,

or an idea by a specific sponsor who paid for the advertisement through mass media such as
radio and television; (b) personal selling, which involves direct personal contact between seller
and the buyer, in such a way that the seller provides the necessary information to the buyer so
as to be convinced on the importance of the product or service (Anderson et al., 2020); (c) sales
promotion, is regarded as the special sales presentations or as part of marketing
communication (Santoso et al., 2019; Yang & Mattila, 2020); (d) publicity, is considered as the
unpaid promotional activity which is mostly carried out by external parties with the sole aim
of spreading positive of negative news concerning a particular company and its products or
services by the media (Abimbola et al., 2020); (e) public relations, is seen as the promotional
element which is concerned about building the reputation of the company or individuals
through communication with the targeted audience as well as the media (Abimbola et al., 2020;
Martha et al., 2019; Qasem et al., 2022).
Customer Trust
Customer trust can simply be considered as the entire customer information as well as
conclusion drawn about particular products, advantages, and attributes (Irfan et al., 2022). It
can also be seen as the wish for another individual to behave in accordance with one’s
expectations (Rafdinal & Amalia, 2019). Hence, consumers tends to have a higher level of trust
in a company’s products when they have positive experience with such company (Jalantina,
2022).
HYPOTHESES DEVELOPMENT
Promotional Mix and Customer Use Decision
Several studies have conducted in an attempt to examine the relationship between promotional
mix and customer use decision in several context. For instance, the study conducted by Tafa,
(2018) to explore the connection between promotional mix and customer use decision in
Ethiopia telecommunication sector using 403 customers as sample size. The outcome revealed
that promotional mix such as public relation, personal selling, seles promotion, advertising
have positive and significant effect on customer use decision. Likewise, Abdelhady et al., (2019)
examines the influence of promotional mix on customers’ buying decision in Airlines using 600
passengers as respondents. The result also suggested that promotional mix has positive and
significant influence on customers’ use decision. In addition, a study was conducted by Yeboah,
(2021)to investigate the link between promotional mix (sales promotion, advertising, personal
selling, public relations, and publicity) and customers’ use decision in Ghana with 200
customers as respondents. The findings indicated that promotional mix is positively related to
customers’ use decision. Accordingly, the current study hypothesized that;
➢ H1: Promotional mix has significant and positive relationship with customers’ use
decision
Promotional Mix and Consumer Trust
Many researches have been carried out in an attempt to examine the relationship between
promotional mix and consumer trust in different context. For example, Rafdinal et al., (2021)
examines the connection between promotional mix and consumer trust with 200 participants
from technical institution. The result show a positive relationship between promotional mix
and consumer trust. Again, Mishbakhudin & Aisyah, (2022) carried out an investigation based
on online marketplace Tokopedia during Covid-19 pandemic on the effect of e-promotion on
